Hadith.1337 - Sama'a ibn Mehran asked Imam Jafar ibn Muhammad Al-Sadiq (as) about a man who encounters a wild beast, and the time for prayer has arrived, but he cannot walk due to fear of the lion. Imam (as) said: "He should face the lion and perform the prayer, gesturing with his head while standing, even if the lion is not in the direction of the Qibla."

Hadith.1339 – Zurarah narrated from Imam Muhammad ibn Ali Al-Baqir (as): I asked him about the prayer of fear and the prayer of travel—are both to be shortened? Imam (as) said: "Yes, and the prayer of fear is more deserving of being shortened than the prayer of travel because it involves fear”.

Hadith.1340 - I heard our teacher, Muhammad ibn al-Hasan, say: It was narrated that Imam Jafar ibn Muhammad Al-Sadiq (as) was asked about the words of Allah (swt), the Mighty and Majestic: "And when you travel throughout the land, there is no blame upon you for shortening the prayer, if you fear that those who disbelieve may harm you" (Surah An-Nisa 4:101). Imam (as) said: "This refers to a second form of shortening, where a man reduces two rak'ahs to one."
