The Prophet (may Allah's peace and blessings be upon him) used to teach his Ummah to resign to Allah Almighty if a calamity strikes them and to resort to His power and strength, Exalted be He, for He is the One Who predestined everything and from Whom compensation comes. In this Hadīth, the Mother of the Believers ’Umm Salamah (may Allah be pleased with her) reports that the Prophet (may Allah's peace and blessings be upon him) said: "When you visit a sick or dead person, say good things." The command here is meant to discipline and teach people what to say when visiting a dead person, i.e., a dying person or a sick person on his deathbed. Supplication is to be made for the ill person, asking Allah to cure him, and for the dead person, asking Allah to have mercy on him and forgive him. The Prophet (may Allah's peace and blessings be upon him) justified this saying that the angels who are present with the afflicted person - like the angel of death and his aids, or other angels in general - say "Amen" to whatever is said by the people who are present. They say: Āmīn, which means: O Allah, answer the supplication. The angels' supplication is readily answered; hence, one must not supplicate with something that could harm him or others. Then, ’Umm Salamah (may Allah be pleased with her) reported that when her husband Abu Salamah (may Allah be pleased with him) died - and he was her husband before the Prophet (may Allah's peace and blessings be upon him) - she went to the Prophet (may Allah's peace and blessings be upon him) and informed him of the death of her husband Abu Salamah (may Allah be pleased with him) expressing her pain and grief about him, not telling the Messenger of Allah (may Allah's peace and blessings be upon him) of her husband's death, for it was reported in Sahīh Muslim Collection that the Messenger of Allah (may Allah's peace and blessings be upon him) attended the death of Abu Salamah (may Allah be pleased with him). The Prophet (may Allah's peace and blessings be upon him) guided and advised her to supplicate Allah, resign to Him, and ask Him for a compensation better than him by saying: "O Allah, forgive me and him," asking forgiveness for her sins and those of her departed one. "And compensate me with someone better than him," i.e., grant me a good compensation and a better substitute. She then reported that Allah Almighty answered her supplication and granted her a better substitute, as the Messenger of Allah (may Allah's peace and blessings be upon him) married her. The Hadīth clarifies that the angels are present with the sick person and say "Amen" to whatever supplication is made by people therein..
