Tahdhīb al-Aḥkām|Volume 2|Book 1|Chapter 6
مُحَمَّدُ بْنُ أَحْمَدَ بْنِ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ عُثْمَانَ بْنِ عِيسَى عَنْ خَالِدِ بْنِ نَجِيحٍ عَنِ اَلصَّادِقِ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ:« اَلتَّكْبِيرُ جَزْمٌ فِي اَلْأَذَانِ مَعَ اَلْإِفْصَاحِ بِالْهَاءِ وَ اَلْأَلِفِ»
Muhammad ibn Ahmad ibn Yahya from Ahmad ibn Muhammad from Uthman ibn Isa from Khalid ibn Najeeh:
(Imam) Al-Sadiq عليه السلام, peace be upon him, said: “The Takbir is to be pronounced firmly in the Adhan with clear articulation of the ‘ha’ and the Alif’.”
