7 حَدَّثَنِي مُحَمَّدُ بْنُ الْحَسَنِ بْنِ عَلِيِّ بْنِ مَهْزِيَارَ عَنْ أَبِيهِ عَنْ جَدِّهِ عَلِيِّ بْنِ مَهْزِيَارَ عَنِ الْحَسَنِ بْنِ سَعِيدٍ عَنْ ظَرِيفِ بْنِ نَاصِحٍ عَنْ خَالِدٍ الْقَلَانِسِيِّ قَالَ سَمِعْتُ أَبَا عَبْدِ اللَّهِ (ع) يَقُولُ صَلَاةٌ فِي مَسْجِدِ الْكُوفَةِ بِأَلْفِ صَلَاةٍ
7. Muḥammad ibn Ḥasan ibn ‘Ali ibn Mahziyār narrated to me from his father, from his grandfather ‘Ali ibn Mahziyār, from Ḥasan ibn Sa’īd, from Żarīf ibn Nāsiḥ, from Khālid Al-Qalānisi, who said: I heard Abā ‘Abdillāh (Imam Sādiq ) say, “Establishing one prayer in the Mosque of Kūfah is equal to establishing one thousand prayers (elsewhere).”
