Narrated Ash-Shu`bi:
حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ ، حَدَّثَنَا إِسْمَاعِيلُ ابْنُ عُلَيَّةَ ، حَدَّثَنَا خَالِدٌ الْحَذَّاءُ ، عَنِ ابْنِ أَشْوَعَ ، عَنِ الشَّعْبِيِّ ، حَدَّثَنِي كَاتِبُ الْمُغِيرَةِ بْنِ شُعْبَةَ ، قَالَ كَتَبَ مُعَاوِيَةُ إِلَى الْمُغِيرَةِ بْنِ شُعْبَةَ أَنِ اكْتُبْ، إِلَىَّ بِشَىْءٍ سَمِعْتَهُ مِنَ النَّبِيِّ، صلى الله عليه وسلم. فَكَتَبَ إِلَيْهِ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " إِنَّ اللَّهَ كَرِهَ لَكُمْ ثَلاَثًا قِيلَ وَقَالَ، وَإِضَاعَةَ الْمَالِ، وَكَثْرَةَ السُّؤَالِ " .
The clerk of Al-Mughira bin Shu`ba narrated, "Muawiya wrote to Al-Mughira bin Shu`ba: Write to me something which you have heard from the Prophet (p.b.u.h) ." So Al-Mughira wrote: I heard the Prophet saying, "Allah has hated for you three things: -1. Vain talks, (useless talk) that you talk too much or about others. -2. Wasting of wealth (by extravagance) -3. And asking too many questions (in disputed religious matters) or asking others for something (except in great need). (See Hadith No. 591, Vol. Ill)
