15 وَ عَنْهُ عَنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ أَبِيهِ عَلِيِّ بْنِ مَهْزِيَارَ عَنْ أَبِيهِ عَنِ الْحَسَنِ بْنِ سَعِيدٍ عَنْ ظَرِيفِ بْنِ نَاصِحٍ عَنْ خَالِدٍ الْقَلَانِسِيِّ قَالَ سَمِعْتُ أَبَا عَبْدِ اللَّهِ (ع) يَقُولُ الصَّلَاةُ فِي مَسْجِدِ الْكُوفَةِ بِأَلْفِ صَلَاةٍ
15. Abū ‘Abdil Raḥmān Muḥammad ibn Aḥmad ibn Ḥusain Al-‘Askari narrated to me from Ḥasan ibn ‘Ali, from his father, from Ḥasan ibn Sa’īd, from Żarīf ibn Nāsiḥ, from Khālid Al-Qalānisi, who said: Abū ‘Abdillāh (Imam Sādiq ) said: Establishing one prayer in the Mosque of Kūfah is equal to establishing one thousand prayers (elsewhere).
