Amir bin Sa'd bin Abi Waqqas (may Allah have mercy on him) says that his father (Sa'd bin Abi Waqqas, may Allah be pleased with him) informed him that in the year of the conquest of Makkah he fell ill in Makkah and in that illness he feared he would die, and the Prophet (peace and blessings be upon him) came to visit him. I said: O Messenger of Allah! Will I be left behind from my emigration? He (peace and blessings be upon him) said: "You will certainly not be left behind after me; so keep doing good deeds, and whatever you do for the pleasure of Allah, Allah Almighty will keep raising your station and rank through it. And it may also be that you are left behind, and that through you Allah benefits some people and harms others." Then he (peace and blessings be upon him) supplicated: 'Allahumma amdi li-ashabi hijratahum wa la taruddahum ala a'qabihim' (O Allah, complete the emigration of my Companions and do not turn them back on their heels). But the poor Sa'd bin Khawlah (may Allah be pleased with him) - he would lament for him that he died in Makkah itself.
