Imam Al-Nawawi’s Riyad-us-Saliheen
About Begging in the Name of Allah
1722. Jabir (May Allah be pleased with him) said: The Messenger of Allah (sallallaahu alayhi wa sallam) said, “No one should ask in the Face of Allah for anything except Jannah.”
1723. Ibn `Umar (May Allah be pleased with them) said: The Messenger of Allah (sallallaahu alayhi wa sallam) said, “Grant shelter to him who begs for it in the Name of Allah, give to him who begs in the Name of Allah, accept the invitation of him who invites you, and requite him who does a favour to you, but if you are unable to requite him, go on praying for him till you are sure that you have requited him adequately.”
[Abu Dawud and An-Nasa’i].
