Bukhari

Hadith Footnote:
This hadith and its note have already been written earlier. Here, it is also worth remembering this verse by the late Iqbal:
"The desert was not enough, we did not spare the sea either;
We made our horses gallop even in the ocean of darkness."

Hadith Commentary:
In one hadith, the Noble Prophet (sallallahu alayhi wa sallam) said:
"Whoever travels by sea during a time of storm, there is no responsibility upon him. If he suffers harm, let him blame himself." (Musnad Ahmad 5/271 and Silsilat al-Ahadith al-Sahihah 2/472, Hadith 828)

In view of this hadith, some scholars have not considered sea travel to be permissible. Imam Malik (rahimahullah) has declared it absolutely impermissible for a woman to travel by sea, even though the statement of Allah, the Exalted, is:
﴿هُوَ الَّذِي يُسَيِّرُكُمْ فِي الْبَرِّ وَالْبَحْرِ ﴾ "He is the One Who enables you to travel on land and at sea." ( Yūnus: 10/22)

Imam Bukhari (rahimahullah) has established from this hadith that traveling by sea for jihad is permissible, and there is no distinction between men and women in this regard. Similarly, for Hajj as well, sea travel is permissible for both men and women.

The reconciliation between both narrations is as follows: the prohibition applies in the case when the sea is stormy or when the journey is without necessity. Traveling for jihad or for commercial purposes is permissible.

It is explicitly mentioned in this hadith that Umm Haram (radi Allahu anha) traveled by sea for jihad. This journey took place during the caliphate of Uthman (radi Allahu anhu), when the Muslims, under the command of Amir Muawiyah (radi Allahu anhu), attacked Rome and conquered it.
May Allah be pleased with them all.

Hadith Commentary:
The dreams of the Prophets (alayhimus-salam) are themselves revelation (wahy) and inspiration (ilham).
You (sallallahu alayhi wa sallam) saw in a dream that some people from your ummah, with great dignity and grandeur, were riding over the sea like kings.
Eventually, this dream of yours was fulfilled, and during the era of Muawiyah (radi Allahu anhu), the Muslims prepared a naval fleet and attacked the region of Sham (Greater Syria). The translation of the chapter heading is thus derived: although Umm Haram (radi Allahu anha) died after falling from an animal, the Messenger of Allah (sallallahu alayhi wa sallam) included her among the mujahideen (those who strive in Allah’s cause), and with the words "You are among the first ones," he (sallallahu alayhi wa sallam) made a prophecy regarding her.

Hadith Commentary:
➊
The dreams of the Prophets (alayhimus-salam) are also revelation (wahy).
The Messenger of Allah (sallallahu alayhi wa sallam) saw in a dream that some people of this Ummah, with great dignity and grandeur, were riding over the sea like kings. Eventually, this dream of his was fulfilled.

➋
During the caliphate of Uthman (radi Allahu anhu), a battle was fought against the Romans.
He appointed Amir Muawiyah (radi Allahu anhu) as the commander-in-chief in this battle.
He prepared a naval fleet and attacked Syria.
Umm Haram (radi Allahu anha) was also with them, and while boarding, she fell and passed away.

➌
Imam Bukhari (rahimahullah) has established from this that although she died from falling, the Messenger of Allah (sallallahu alayhi wa sallam) included her among the mujahideen, as he had foretold in his prophecy that "You are among the first group."

Benefits and Issues:
➊
This hadith is explicitly and clearly among the evidences of Prophethood.
Because in it, the Messenger of Allah (sallallahu alayhi wa sallam) informed about something that occurred after his (sallallahu alayhi wa sallam) passing.
No one except Allah, the Mighty and Majestic, could have known this.
Therefore, the Messenger of Allah (sallallahu alayhi wa sallam) was informed of it through revelation (wahy).

➋
This pertains to the year 28 AH, during the caliphate of Uthman (radi Allahu anhu).
At that time, Muawiyah bin Abu Sufyan (radi Allahu anhu) was the commander of this military expedition.
Therefore, this also establishes the virtue and merit of Muawiyah (radi Allahu anhu).
Likewise, it establishes the virtue of those noble Companions (radi Allahu anhum ajma'in) who accompanied him on this naval expedition.
This was a military expedition (jihad).

➌
It is permissible to laugh at something pleasing and delightful.

Benefits and Issues:
By this is meant the journey of jihad or the journey of Hajj and ‘Umrah.
Other sea journeys which are journeys of obedience should also be expected to have this virtue.

(1) "Married" — It is as if, at the time of this dream, she was not yet in his marriage. The marriage took place later. And in this expedition, she had gone along with her husband, ‘Ubada ibn Samit (radi Allahu anhu), which is why, in the translation of the previous hadith, this point was clarified through parentheses.
(2) "Came out from the sea" — Her blessed grave is on the island of Cyprus. Thus, when she reached this island and came out from the sea, this incident occurred. Radi Allahu anhu wa ardaaha.
(3) Her going with the army was for the service of her honorable husband and the wounded mujahideen, not to participate in fighting, because for women, joining in battle is not permissible due to the lack of veiling, and there is also the danger of falling into the hands of the disbelievers.

Benefits and Issues:
(1)
The very first naval force of the Muslims was prepared by Muawiyah (radi Allahu anhu).
This was during the caliphate of Uthman (radi Allahu anhu).
The expedition in which Umm Haram (radi Allahu anha) participated was the first naval campaign, which took place in 28 AH. (Fath al-Bari, al-Jihad, Chapter: The Expedition of a Woman by Sea: 2/94)

(2)
It is permissible to supplicate or have someone supplicate for the attainment of a virtue.

(3)
The fulfillment of the prophecy of the Messenger of Allah (sallallahu alayhi wa sallam) is proof of his truthfulness.

(4)
A woman may participate in jihad along with her mahram or husband.

(5)
Accidental death is also martyrdom (shahadah).

(6)
The praise of those who participate in naval warfare establishes their virtue.
The air force, in one respect, is similar to the navy.
In fact, in some respects, it is superior to it; therefore, this virtue applies to the air force as well as the navy. However, the importance of the land army cannot be denied.

Benefit:
There are various ranks of martyrdom; the most superior martyr is the one who is martyred in battle at the hands of the disbelievers. Apart from this, in the hadith, those who die from various illnesses have also been referred to as martyrs. Furthermore, from this hadith, the virtue of Sayyidah Umm Haram radi Allahu anha is also established.
