Umar bin Abi Salamah narrated from his father, who said:
حَدَّثَنَا يَحْيَى بْنُ مُوسَى ، أَخْبَرَنَا عَمْرُو بْنُ عَوْنٍ ، أَخْبَرَنَا أَبُو عَوَانَةَ ، عَنْ عُمَرَ بْنِ أَبِي سَلَمَةَ ، عَنْ أَبِيهِ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لِيَنْظُرَنَّ أَحَدُكُمْ مَا الَّذِي يَتَمَنَّى فَإِنَّهُ لاَ يَدْرِي مَا يُكْتَبُ لَهُ مِنْ أُمْنِيَّتِهِ " . هَذَا حَدِيثٌ حَسَنٌ .
“The Messenger of Allah (ﷺ) said: ‘Let one of you look at what it is that he wishes for. For verily, he does not know what of his wish shall be recorded.’”
