Do not recite (Quran) while you are in Ruk’u nor when you -asws are in Sajdah...
Do not recite (Quran) while you are in Ruk’u nor when you -asws are in Sajdah, and do not pray Salat and you -asws have plaited your -asws hair, for it is a portion of Satan -la , and do not do Al-Iq’a (sitting in thunderbolt pose) between the two Sajdah(s)’’. وَ يُؤَيِّدُهُ مَا وَرَدَ فِي حَدِيثِ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ ع وَ لَا تُقْعِ عَلَى قَدَمَيْكَ.
And it is supported by what has been referred in a Hadeeth by Zurara, from Abu Ja’far -asws : ‘Do not do Al-Iq’a (sitting in thunderbolt pose) upon your feet’’. و الدليل على أن النهي ليس للتحريم ما رواه عُبَيْدُ اللَّهِ الْحَلَبِيُّ عَنْ أَبِي عَبْدِ اللَّهِ ع قَالَ: لَا بَأْسَ بِالْإِقْعَاءِ فِي الصَّلَاةِ بَيْنَ السَّجْدَتَيْنِ.
And the evidence upon that the prohibition isn’t forbiddance is what is reported by Ubedullah Al-Halby, from Abu Abdullah -asws having said: ‘There is no problem with Al-Iq’a (sitting in thunderbolt pose) between the two Sajdah(s)’’. زرارة عن الباقر ع كراهيته حيث قال و إياك و القعود على قدميك فتتأذى بذلك. Zurara from Al-Baqir -asws is its abhorrence whereby he -asws said: ‘And beware of the sitting upon your feet for you will be hurt by that’’.
وَ مِنْ طَرِيقِ الْأَصْحَابِ مَا رَوَاهُ أَبُو بَصِيرٍ عَنْ أَبِي عَبْدِ اللَّهِ ع قَالَ: لَا تُقْعِ بَيْنَ السَّجْدَتَيْنِ. And from the ways of the companions is what is reported by Abu Baseer, from Abdullah -asws having said: ‘Do not do Al-Iq’a (sitting in thunderbolt pose) between the two Sajdah(s)’’.
And from him, copying from the book of Hareyz who said, ‘Abu Ja’far -asws said: ‘There is no problem with Al-Iq’a (sitting in thunderbolt pose) in what is between the two Sajdahs, and Al-Iq’a is not appropriate between the Tashahhud and the sitting, and rather the Tashahhud is in the sitting, and the one sitting in Al-Iq’a posture is no sitting’’.
