It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Do not assign My sinful servants who know Me and affirm My Oneness to Paradise or to Hell, until I Myself assign them their abode according to My knowledge of them. And do not burden yourselves in this matter with what you have not been charged with, and do not take the servants to account in place of their Lord."
