بَابُ قَوْلِ اللَّهِ تَعَالَى: {لاَ يَسْأَلُونَ النَّاسَ إِلْحَافًا} وَكَمِ الْغِنَى
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 ‏"‏‏.‏
