It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever helps one of his brothers in meeting his need and treats him with kindness and courtesy, it becomes a right binding upon the generosity of Allah Almighty that He appoints the servants of Paradise to serve him." Similarly, it is narrated through another chain that the Messenger of Allah (peace and blessings be upon him) said: "Whoever treats a believer with gentleness and kindness, or supports him in any of his needs, whether small or great (will also receive this same reward)."
I (Ibn Hajar) say: The central pivot of the chains of this hadith is the narrator named Yazid al-Raqashi, and he is weak.
