Bukhari

Hadith Commentary: Hafiz said: In the same way, it is forbidden for a man to look at the private parts (‘awrah) of a non-mahram woman, and for a woman to look at the private parts of a non-mahram man.

From this hadith, it is understood that a man should also not touch the body of another man except out of necessity, and it is permissible to shake hands at the time of greeting.

Similarly, embracing (mu‘anaqah) and kissing are also prohibited, except that embracing is permissible for someone who has returned from a journey.

In the same way, a father may kiss his children out of affection.

It is permissible to kiss the hand of a righteous person out of love, as the Companions (radi Allahu anhum) used to do with the Prophet (sallallahu alayhi wa sallam), but it is not permissible to kiss the hand of a worldly leader because of his wealth.

(Wahidi)

As for the so-called pirs and mashayikh of today who have their hands and feet kissed, this is absolutely impermissible.

Remember regarding kissing that there are five types of kisses, and only these situations are permissible; any other situation that is considered permissible is not allowed:

(1) The kiss of parenthood: a father or mother kisses their child.

(2) The kiss of filial piety: a child kisses their parents.

(3) The kiss of affection: a companion kisses a companion, or a peer kisses a peer.

(4) The kiss of compassion: an elder kisses a younger.

The place for these types is the hand or the forehead, not the cheek.

(5) The kiss of desire: a husband and wife kiss each other.

(‘Abd al-Rashid Tunisi)

Hadith Commentary:
The Messenger of Allah (sallallahu alayhi wa sallam) issued this prohibitive command because if a woman describes the beauty and attractiveness of another woman to her husband, there is a danger that he may be put to trial; for if he becomes fond of the other woman's beauty, he may attempt to divorce his wife and marry her.

If that woman is already married, then this man's relationship with his own wife will deteriorate, and his wife will lose her value and status in his eyes.

And if she describes the ugliness of any woman, then this falls under the category of backbiting (ghibah), which is religiously forbidden.

Hadith Commentary:
The wisdom in this prohibition is the fear that the husband, upon hearing the description of the woman, may become enamored with her and, as a result, divorce the one who described her or become infatuated with the one who was described (Fath al-Bari).
That is, the wisdom in this prohibition is that there is a fear that the husband, upon hearing the appearance of that woman, may become so captivated by her that he divorces his own wife or becomes entangled in temptation regarding the one described.

Furthermore, it is also necessary that one man does not look at the private parts of another, as this too is a cause for curse.

Today, Westernized people stand in public pathways and urinate, openly displaying their shamelessness. Such Muslims should fear Allah, for one day they will inevitably have to stand before Him.

And with Allah is all success.

Hadith Commentary:
(1)
In one narration it is stated:
“No man should look at the private parts (‘awrah) of another man, and no woman should look at the private parts (‘awrah) of another woman.”
(Sahih al-Bukhari, Virtues of the Companions of the Prophet sallallahu alayhi wa sallam, Hadith: 768 (338))

Imam Nawawi rahimahullah, in light of this hadith, has written that it is forbidden (haram) for a man to look at the private parts (‘awrah) of another man, and similarly, it is impermissible (najā’iz) for a woman to look at the private parts (‘awrah) of another woman. Likewise, it is forbidden for a man to look at the ‘awrah of a non-mahram woman, and for a woman to look at the ‘awrah of a non-mahram man. However, husband and wife are exempted from this.
(Fath al-Bari: 9/420)

(2)
In any case, this act is a cause of curse, but today, Westernized people stand in public thoroughfares and urinate, thus committing open indecency. Muslims should avoid such filthy imitation.

Explanation:
1:
If a woman describes the physical attributes of another woman to her husband, this may lead her husband into temptation and adultery. The Shariah has prohibited describing the physical attributes of another woman precisely to prevent such temptation.

Benefits and Issues:
If a woman lies down or sleeps with another woman and then describes her condition to her husband, or begins to praise someone in this manner, it is prohibited and impermissible. Such situations become a cause for satanic whispers to arise in the hearts, and then tribulations emerge. The same teaching applies to the husband as well: he should not excessively praise any man in front of his wife.
