Sayyiduna Amir bin Umayr (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) stayed in for three days and did not come out for the obligatory prayer. When this was mentioned to him, he said: "I have found my Lord Glorious and Generous. Along with each one of the seventy thousand people who will enter Paradise without any reckoning, He has granted me a further seventy thousand people. I said: 'My nation will not reach this number,' or 'complete it?' He said: 'I will complete them for you by means of the Bedouins.'"
Al-Tabarani recorded it, and its narrators are the narrators of the Sahih except al-Tabarani's teacher, whose case is different. There is also idtirab (inconsistency) in this narration regarding the name of the Companion: according to one view his name is Sayyiduna Amr bin Umayr, according to another Sayyiduna Umayr bin Amr, according to another Sayyiduna Umarah bin Umayr, according to another Sayyiduna Amr bin Hazm, and according to another Sayyiduna Amr bin Bilal.
