5- الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنِ الْوَشَّاءِ عَنْ أَبِي الْحَسَنِ (عَلَيْهِ السَّلام) قَالَ سَمِعْتُهُ يَقُولُ إِنَّ اللهَ عَزَّ وَجَلَّ يُبْغِضُ الْقِيلَ وَالْقَالَ وَإِضَاعَةَ الْمَالِ وَكَثْرَةَ السُّؤَالِ.
5. Al-Husayn from Muhammad has narrated from Mu’alla’ ibn Muhammad from al-Washsha’ who has said the following: “I once heard abu al-Hassan (a.s.), saying, ‘Allah, most Majestic, most Glorious, hates qil (it was said so), qal (he said so and so on . . .), wasting assets and asking a great deal of questions.’”
