وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ الْحَنْظَلِيُّ، أَخْبَرَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنِ الشَّعْبِيِّ، عَنْ وَرَّادٍ، مَوْلَى الْمُغِيرَةِ بْنِ شُعْبَةَ عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ " إِنَّ اللَّهَ عَزَّ وَجَلَّ حَرَّمَ عَلَيْكُمْ عُقُوقَ الأُمَّهَاتِ وَوَأْدَ الْبَنَاتِ وَمَنْعًا وَهَاتِ وَكَرِهَ لَكُمْ ثَلاَثًا قِيلَ وَقَالَ وَكَثْرَةَ السُّؤَالِ وَإِضَاعَةَ الْمَالِ " .
Mughira b. Shu'ba reported Allah's Messenger (ﷺ) as saying: Verity Allah, the Glorious and Majestic, has forbidden for you: disobedience to mothers, and burying alive daughters, withholding the right of others in spite of having the power to return that to them and demanding that (which is not one's legitimate right). And He disapproved three things for you; irrelevant talk, persistent questioning and wasting of wealth.
