Silsilat al-Ahadith al-Sahihah

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Do you know about that group from my Ummah who will be the first to enter Paradise?" I said: Allah and His Messenger know best. He (peace and blessings be upon him) said: "That group is of the Muhajirun (Emigrants). On the Day of Resurrection, they will come to the gate of Paradise and demand that it be opened. The gatekeeper will ask them: Has your reckoning been completed? They will say: On what matter should we be reckoned? Our swords remained on our shoulders in the path of Allah until we died. So, the gatekeeper will open the door for them, and they (after entering) will have already taken a nap of forty years before the general people enter."
