Takbir, Allah-azwj is Great beyond description
رَفَعَ يَدَيْهِ وَ قَالَ: «اللَّهُ أَكْبَرُ» وَ أَثْنَى عَلَى اللَّهِ تَعَالَى بَعْدَهُ قَالَ اللَّهُ لِمَلَائِكَتِهِ: أَ مَا تَرَوْنَ عَبْدِي هَذَا كَيْفَ كَبَّرَنِي
(6th Imam-asws said) ‘And when he lifts his hands and says: ‘Allah-azwj is Great (beyond any description)!’, and starts extolling Allah-azwj, Allah-azwj Says to the Angels: ‘Do you see this servant of Mine-azwj, how he considers Me-azwj to be beyond any description (The most High) (an extract).[1]
عَلِيُّ بْنُ إِبْرَاهِيمَ بْنِ هَاشِمٍ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ جَمِيلٍ وَ مُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ جَمِيلِ بْنِ دَرَّاجٍ عَنْ زُرَارَةَ قَالَ سَأَلْتُ أَبَا جَعْفَرٍ ( عليه السلام ) عَنِ الرَّجُلِ يَنْسَى تَكْبِيرَةَ الِافْتِتَاحِ قَالَ يُعِيدُ
Ali Bin Ibrahim Bin Hashim, from his father, from Ibn Abu Umeyr, from Jameel, and Muhammad Bin Ismail, from Al Fazl Bin Shazaan, from Ibn Abu Umeyr, from Jameel Bin Darraj, from Zurara who said,
‘I asked Abu Ja’far-asws about the man who forgets the exclamation of Takbīr in the beginning. He-asws said: ‘He should repeat’.[2]
Salat without reciting Allāhu ʾAkbar (اللَّهُ أَكْبَرُ) – Takbir is not accepted:
الْحُسَيْنُ بْنُ مُحَمَّدٍ الْأَشْعَرِيُّ عَنْ عَبْدِ اللَّهِ بْنِ عَامِرٍ عَنْ عَلِيِّ بْنِ مَهْزِيَارَ عَنْ فَضَالَةَ عَنْ أَبَانٍ عَنِ الْفَضْلِ بْنِ عَبْدِ الْمَلِكِ أَوِ ابْنِ أَبِي يَعْفُورٍ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) أَنَّهُ قَالَ فِي الرَّجُلِ يُصَلِّي فَلَمْ يَفْتَتِحْ بِالتَّكْبِيرِ هَلْ تُجْزِئُهُ تَكْبِيرَةُ الرُّكُوعِ قَالَ لَا بَلْ يُعِيدُ صَلَاتَهُ إِذَا حَفِظَ أَنَّهُ لَمْ يُكَبِّرْ
AI-Hussain ibn Mohammed al-Ash’ariy has narrated from’ Abd Allah ibn ‘Amir from Ali ibn Mahziyar from Fadalah from Aban from al- Fadalah ‘Abd aI-Malik or ibn abu Ya’fur:
About a man who perform Salat but forgets to say the opening Takbir (Allah is Great beyond description) or Takbir (Allah is great beyond description) for Ruku’ (bowing down on one’s knees) is it sufficient? Abu ‘Abd Allah-asws has said: ‘It is not sufficient. He performs Salat again when he finds out that he has not said the Takbir.’[3]
