Narrated Abu Aiyub:
A man said to the Prophet (ﷺ) "Tell me of such a deed as will make me enter Paradise." The people said, "What is the matter with him? What is the matter with him?" The Prophet (ﷺ) said, "He has something to ask. (What he needs greatly) The Prophet (ﷺ) said: (In order to enter Paradise) you should worship Allah and do not ascribe any partners to Him, offer prayer perfectly, pay the Zakat and keep good relations with your Kith and kin." (See Hadith No. 12, Vol 8).
Narrated Abu Aiyub Al-Ansari:
A man said, "O Allah's Messenger! Inform me of a deed which will make me enter Paradise." The people said, "What is the matter with him? What is the matter with him?" Allah's Messenger (ﷺ) said, "He has something to ask (what he needs greatly)." The Prophet (ﷺ) said (to him), (In order to enter Paradise) you should worship Allah and join none in worship with Him: You should offer prayers perfectly, give obligatory charity (Zakat), and keep good relations with your Kith and kin." He then said, "Leave it!" (The sub-narrator said, "It seems that the Prophet (ﷺ) was riding his she camel."
It is narrated on the authority of Abu Ayyub Ansari that once during the journey of the Prophet (may peace of Allah be upon him) a bedouin appeared before him and caught hold of the nosestring of his she-camel and then said, Messenger of Allah (or Muhammad), inform me about that which takes me near to Paradise and draws me away from the Fire (of Hell). He (the narrator) said: The Prophet (ﷺ) stopped for a while and cast a glance upon his companions and then said: He was afforded a good opportunity (or he had been guided well). He (the Holy Prophet) addressing the bedouin said: (Repeat) whatever you have uttered. He (the bedouin) repeated that. Upon this the Apostle (ﷺ) remarked: The deed which can draw you near to Paradise and take you away from Hell is, that you worship Allah and associate none with Him, and you establish prayer and pay Zakat, and do good to your kin. After having uttered these words, the Prophet (ﷺ) asked the bedouin to release the nosestring of his she-camel.
