حَدَّثَنَا مُسَدَّدٌ، قَالَ: حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ عُمَرَ بْنِ أَبِي سَلَمَةَ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: ”إِذَا تَمَنَّى أَحَدُكُمْ فَلْيَنْظُرْ مَا يَتَمَنَّى، فَإِنَّهُ لاَ يَدْرِي مَا يُعْطَى.“
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "When any of you wishes for something, he should see what he is wishing for, because he does not know what will be given to him."
