Ibn ‘Abbas said that when ‘Ali came out after visiting the Prophet during the painful illness of which he died, the people asked, “How is God's messenger this morning, Abul Hasan?” He replied, “Praise be to God, he is getting better.”
Abu Huraira reported God’s messenger as saying, '"If anyone visits an invalid, one cries out from heaven, ‘May you be good, may your walk be good, and may you come to an abode in paradise!”’
Narrated ‘Ata’ b. Abu Rabah said Ibn ‘Abbas asked whether he would like him to show him a woman who would go to paradise. When he replied that he certainly would, he said:
This black woman came to the Prophet and said, “Messenger of God, I am subject to fits and become uncovered, so make supplication to God for me.” He replied, “If you wish you may endure it and be rewarded with paradise, but if your wish I shall make supplication to God to cure you.” She said, “I shall endure it.” Then she added, “But since I become uncovered, make supplication to God that that may not happen.” He then made supplication for her.
Anas told that when a young Jew who was a servant of the Prophet became ill the Prophet went to visit him and, sitting down by his head, said to him, “Accept Islam.” He looked at his father who was beside him, and he said, "Obey Abul Qasim.” So he accepted Islam, and the Prophet went out saying, "Praise be to God who has saved him from hell.”
