Ahmad ibn Muhammad has narrated from Ali ibn al-Hakam from Aban from ‘Abd al-Rahman ibn abu ‘Abd Allah who has said the following: “I once asked abu ‘Abd Allah (a.s.), about the words of Allah, most Majestic, most Glorious, ‘...

if you are afraid then it is on foot or riding....’(2:240), ‘How is this Salah (prayer) performed and what do you say if one is afraid of beasts or thieves?’ He (the Imam) said, ‘He says Takbir (Allah is great beyond description) and makes gestures with his head as gestures are made.’” وثق - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (15/426))
