It is narrated on the authority of Abu Hurairah and Hudhaifah that the Messenger of Allah (peace and blessings of Allah be to him) said: Allah, the Blessed and Exalted, would gather people. The believers would stand till the Paradise would be brought near them. They would come to Adam and say: O our father, open for us the Paradise. He would say: What turned you out from the Paradise was the sin of your father Adam. I am not in a position to do that; better go to my son Ibrahim, the Friend of Allah. He (the Holy Prophet) said: He (Ibrahim) would say: I am not in a position to do that. Verily I had been the Friend (of Allah) from beyond; you better approach Moses with whom Allah conversed. They would come to Moses, but he would say: I am not in a position to do that; you better go to Jesus, the Word of Allah and His Spirit. Jesus would say: I am not in a position to do that. So they would come to Muhammad. He would then be permitted (to open the door of Paradise). Trustworthiness and kinship would be dispatched, and these would stand on the right and left of the Path and the first of you would pass with (the swiftness) of lightening….
(Sahih Muslim)
Trustworthiness and kinship would be the Guide-posts on the Path of ultimate success. He who is trustworthy and undertakes his responsibilities with regard to his kith and kin would find his path to Paradise quite easy and swift.
