2ـ مُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ عَنْ حَمَّادِ بْنِ عِيسَى عَنْ رِبْعِيِّ بْنِ عَبْدِ الله عَنِ الْفُضَيْلِ بْنِ يَسَارٍ قَالَ كَانَ عَلِيُّ بْنُ الْحُسَيْنِ (صلّى اللهُ عَلَيْهِ وَآلِه) يَأْمُرُ الصِّبْيَانَ يَجْمَعُونَ بَيْنَ الْمَغْرِبِ وَالْعِشَاءِ وَيَقُولُ هُوَ خَيْرٌ مِنْ أَنْ يَنَامُوا عَنْهَا.
2. Muhammad ibn ’Isma‘il has narrated from al-Fadl ibn Shadhan from Hammad ibn ‘Isa from Rib‘i ibn ‘Abd Allah from Fudayl ibn Yasar who has said the following: “Ali ibn al-Husayn , would instruct children to perform Salah (prayer) of al-Maghrib and al-‘Isha’ soon, one after the other, saying that it is better for them than falling asleep.”
