ahmad-zuhd:2083ʿAbdullāh > Yūsuf b. Yaʿqūb al-Ṣaffār a freed slave of Banī Umayyah > Abū Bakr b. ʿAyyāsh > ʿĀṣim

[Machine] Abu Wael used to pray in his house with a soft and low voice, even if he was offered the world to pray differently, and no one would have known what he did.  

الزهد لأحمد:٢٠٨٣حَدَّثَنَا عَبْدُ اللَّهِ حَدَّثَنِي يُوسُفُ بْنُ يَعْقُوبَ الصَّفَّارُ مَوْلَى بَنِي أُمَيَّةَ حَدَّثَنَا أَبُو بَكْرِ بْنُ عَيَّاشٍ عَنْ عَاصِمٍ قَالَ

كَانَ أَبُو وَائِلٍ إِذَا صَلَّى فِي بَيْتِهِ يَنْشُجُ نَشْجًا وَلَوْ جُعِلَتْ لَهُ الدُّنْيَا عَلَى أَنْ يَفْعَلَهُ وَأَحَدٌ يَرَاهُ مَا فَعَلَهُ
