Keringanan shalat satu rakaat bagi orang ketika dalam keadaan takut
Imam Nasa'i : 450أَخْبَرَنَا مُحَمَّدُ بْنُ هَاشِمٍ الْبَعْلَبَكِّيُّ قَالَ أَنْبَأَنَا الْوَلِيدُ قَالَ أَخْبَرَنِي أَبُو عَمْرٍو يَعْنِي الْأَوْزَاعِيَّأَنَّهُ سَأَلَ الزُّهْرِيَّ عَنْ صَلَاةِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِمَكَّةَ قَبْلَ الْهِجْرَةِ إِلَى الْمَدِينَةِ قَالَ أَخْبَرَنِي عُرْوَةُ عَنْ عَائِشَةَ قَالَتْ فَرَضَ اللَّهُ عَزَّ وَجَلَّ الصَّلَاةَ عَلَى رَسُولِهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَوَّلَ مَا فَرَضَهَا رَكْعَتَيْنِ رَكْعَتَيْنِ ثُمَّ أُتِمَّتْ فِي الْحَضَرِ أَرْبَعًا وَأُقِرَّتْ صَلَاةُ السَّفَرِ عَلَى الْفَرِيضَةِ الْأُولَى
Narrated to us [Muhammad bin Hasyim AlBa'labaki] he said :Narrated to us [Al Walid] he said : Has informed me [Abu Amr i.e. Al Auza`i] that he once asked Az-Zuhri how the Messenger of Allah shallallahu 'alaihi wasallam prayed while in Makkah (before migrating to Madinah). [Az-Zuhri] replied; Has informed me [Urwah] from [Aisha] Radliyallahu'anha she said : "Allah the Mighty and Majestic made it obligatory for the Messenger of Allah shallallahu 'alaihi wasallam to pray the first time two rak'ahs, then it was perfected to four rak'ahs for those who stayed, and made the travelling prayer two rak'ahs as it was at the beginning.
