وَ قَدْ رُخِّصَ فِي صَلاَةِ اَلْخَوْفِ مِنَ اَلسَّبُعِ إِذَا خَشِيَهُ اَلرَّجُلُ عَلَى نَفْسِهِ أَنْ يُكَبِّرَ وَ لاَ يُومِئَ رَوَاهُ مُحَمَّدُ بْنُ مُسْلِمٍ عَنْ أَحَدِهِمَا عَلَيْهِمَا اَلسَّلاَمُ.

Hadith.1344 - t has been permitted, in the case of the prayer of fear from a wild beast when a person fears for their life, to simply say the takbir (proclaiming "Allahu Akbar") without making gestures. This was narrated by Muhammad ibn Muslim from one of the Imams (as).
