Sahih Muslim , Book 5, Hadith 2258 (USC-MSA) ⓘ
Mu'awiya reported Allah's Messenger as saying: Do not press in a matter, for I swear by Allah, none of you who asks me for anything and manages to get his request while I disdain it, will he be blessed in that which I give him.
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، عَنْ وَهْبِ بْنِ مُنَبِّهٍ، عَنْ أَخِيهِ، هَمَّامٍ عَنْ مُعَاوِيَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ تُلْحِفُوا فِي الْمَسْأَلَةِ فَوَاللَّهِ لاَ يَسْأَلُنِي أَحَدٌ مِنْكُمْ شَيْئًا فَتُخْرِجَ لَهُ مَسْأَلَتُهُ مِنِّي شَيْئًا وَأَنَا لَهُ كَارِهٌ فَيُبَارَكَ لَهُ فِيمَا أَعْطَيْتُهُ " .
