٢ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنِ الْوَشَّاءِ عَنْ أَبَانِ بْنِ عُثْمَانَ عَنْ عُمَرَ بْنِ يَزِيدَ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ الْمُسَافِرِ يُصَلِّي مَعَ الإِمَامِ فَيُدْرِكُ مِنَ الصَّلاَةِ رَكْعَتَيْنِ أَ يُجْزِئُ ذَلِكَ عَنْهُ فَقَالَ نَعَمْ. 
2. Al-Husayn ibn Muhammad has narrated from Mu‘alla’ ibn Muhammad, from al-Washsha’ from Aban ibn ‘Uthman, from ‘Umar ibn Yazid who has said the following: “I once asked abu ‘Abd Allah , about a traveler who performs Salah (prayer) behind an Imam and joins only for two Rak‘at, is it sufficient? He (the Imam) said, ‘Yes, it is sufficient.’”
