Sahih al-Bukhari 1477
Narrated Ash-Shu`bi:
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)
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 ‏"‏‏.‏
