Anas reported that the Muhajirun said, "Messenger of Allah, the
Ansar have taken all the reward!" He said, "No, not as long as you make
supplication for them and praise them for it."
Ibn 'Umar reported that the Messenger of Allah, may Allah bless
him and grant him peace, said, "Anyone who seeks refuge in Allah will find
refuge with Him. Anyone who asks from Allah will be receive. Anyone who
does a favour should repay it. If you do not find anything, then make supplication
for the doer of the favour so that he knows that you have repaid him."
Jabir ibn 'Abdullah al-Ansari reported that the Prophet, may Allah
bless him and grant him peace, said, "Whoever has a favour done for him
should repay it. If he cannot find anything he can use to repay it, he
should praise the one who did it. When he praises him, he thanks him. If
he is silent, he is ungrateful to him. If someone adorns himself with something
he has not been given, it is as if he was wearing a false garment."
