Sahih Bukhari 4587 — Allah’s Statement: “And what is wrong with you

Hadith Commentary:
His mother’s name was Lubabah bint al-Harith radi Allahu anha, who was the sister of Maymunah radi Allahu anha.
Both of them had wholeheartedly accepted Islam, but they were trapped in the hands of the disbelievers in Makkah and were unable to migrate. A verse was revealed regarding them.

Hadith Commentary:
➊
In the noble verse mentioned in the title, Muslims are being encouraged to help the weak and oppressed Muslims and to strive (jihad) against the oppressors in order to save them from tyranny and oppression.
Ibn Abbas (radi Allahu anhu) and his mother were also among those weak Muslims whose assistance was obligatory upon the Muslims.
The Messenger of Allah (sallallahu alayhi wa sallam) used to supplicate for such people after raising his head from bowing (ruku‘), saying:
“O Allah! (Help) Walid bin Walid, Salamah bin Hisham, ‘Ayyash bin Abi Rabi‘ah, and other weak Muslims during the time of famine.”
(Sahih al-Bukhari, al-Adab, Hadith: 6200)
Then, when these weak and oppressed Muslims were freed from the disbelievers of Makkah and arrived in Madinah Tayyibah, the Prophet (sallallahu alayhi wa sallam) ceased making supplications against the disbelievers.
