The Fear prayer has different forms, for the enemy is sometimes in the direction of the Qiblah and sometimes in another direction. The Fear prayer consists sometimes of four Rak`ahs, three Rak`ahs, as for Maghrib, and sometimes two Rak`ah like Fajr and prayer during travel. The Fear prayer is sometimes prayed in congregation, but when the battle is raging, congregational prayer may not be possible. In this case, they pray each by himself, facing the Qiblah or otherwise, riding or on foot. In this situation, they are allowed to walk and fight, all the while performing the acts of the prayer. Some scholars said that in the latter case, they pray only one Rak`ah, for Ibn `Abbas narrated, "By the words of your Prophet , Allah has ordained the prayer of four Rak`ah while residing, two Rak`ah during travel, and one Rak`ah during fear.'' Muslim, Abu Dawud, An-Nasa'i and Ibn Majah recorded it.

This is also the view of Ahmad bin Hanbal. Al-Mundhiri said, "This is the saying of `Ata', Jabir, Al-Hasan, Mujahid, Al-Hakam, Qatadah and Hammad; and Tawus and Ad-Dahhak also prefered it.'' Abu `Asim Al-`Abadi mentioned that Muhammad bin Nasr Al-Marwazi said the Fajr prayer also becomes one Rak`ah during fear. This is also the opinion of Ibn Hazm. Ishaq bin Rahwayh said, "When a battle is raging, one Rak`ah during which you nod your head is sufficient for you. If you are unable, then one prostration is sufficient, because the prostration is remembrance of Allah.''
