A Muslim is a Brother of another Muslim
Ibn Umar (radi Allahu anhum) reported that the Messenger of Allah (sal Allahu alaihi wa sallam) said, “A Muslim is a brother of (another) Muslim, he neither wrongs him nor hands him over to one who does him wrong. If anyone fulfills his brother’s needs, Allah will fulfill his needs; if one relieves a Muslim of his troubles, Allah will relieve his troubles on the Day of Resurrection; and if anyone covers up a Muslim (his sins), Allah will cover him up (his sins) on the Day of Resurrection.”
[Sahih al-Bukhari and Muslim]
This Hadith tells us that we should fulfill the needs of Muslims for the Pleasure of Allah only, regardless of any vested interest or worldly motive. It is a very meritorious approach. The needs of people who adopt this attitude in life are fulfilled by Allah, and the reward they get for it in the Hereafter will be greater than that to be given in this world.
And Allah Knows Best!
