It is narrated from Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him) that a man came to the Messenger of Allah (peace and blessings be upon him) and said: Tell me of a deed that will admit me into Paradise. The people said: What is the matter with him? What is the matter with him? So the Prophet (peace and blessings be upon him) said: "He has a need. Worship Allah and do not associate anything with Him, establish the prayer, give zakah, and maintain the ties of kinship. Now let it (the mount) go."
