The Book of Prayers (Kitab Al-Salat)
Muslim :: Book 4 : Hadith 2003
Umm Salama reported: The Messenger of Allah (may peace be upon came to Abu Salama (as he died). His eyes were fixedly open. He closed them, and then said: When the soul is taken away the sight follows it. Some of the people of his family wept and wailed. So he said: Do not supplicate for yourselves anything but good, for angels say" Amen" to what you say. He then said: O Allah, forgive Abu Salama, raise his degree among those who are rightly guided, grant him a successor in his descendants who remain. Forgive us and him, O Lord of the Universe, and make his grave spacious, and grant him light in it.
