Bulugh al-Maram 538

Umm Salamah (RAA) narrated, ‘The Messenger of Allah (ﷺ) came to see Abu Salamah when his sight had become fixed (with his eyes open, as he had already passed away). So the Prophet (ﷺ), closed his eyes and said, “When the soul is seized and leaves the body, the sight follows it.’ Some of Abu Salamah's family wept and wailed, whereupon the Messenger of Allah said to them, ‘Do not supplicate to Allah anything except that which is good for you (i.e. do not say anything which goes against you at that moment), because the angels (who are present at the time of death), say “Amin" (asking Allah to accept your invocation) to whatever you say.” Then he said, "O Allah! Forgive Abu Salamah, raise his status among (Your) rightly guided servants, make his grave spacious, and fill it with light for him, and be his successor in taking good care of his descendants whom he has left behind, (and make them pious).” Related by Muslim.
