[Machine] Regarding the narration of Idris al-Awadī and Ibn Abī Laylā, both narrated from ʿĀṣim ibn Abī an-Najūd, who narrated from Zirr ibn Ḥubaysh, who narrated from Ṣafwān ibn ʿAssāl, that the Messenger of Allah, ﷺ , prostrated when the sky was split apart.  

عَنْ إِدْرِيسَ الْأَوْدِيِّ وابْنِ أَبِي لَيْلَى كِلَاهُمَا عَنْ عَاصِمِ بْنِ أَبِي النَّجُودِ عَنْ زِرِّ بْنِ حُبَيْشٍ عَنْ صَفْوَانَ بْنِ عَسَّالٍ «أَنَّ رَسُولَ اللهِ ﷺ سَجَدَ فِي إِذَا السَّمَاءُ انْشَقَّتْ»  

The Prophet ﷺ said: The time limit for wiping over the socks for a traveller is three days (and three nights) and for a resident it is one day and one night. Abu Dawud said: Another version adds: Had we requested him to extend (the period of wiping), he would have extended. (Using translation from Abū Dāʾūd 157)   

عَنِ النَّبِيِّ ﷺ فِي الْمَسْحِ عَلَى الْخُفَّيْنِ «لِلْمُسَافِرِ ثَلَاثَةُ أَيَّامٍ وَلَيَالِيهِنَّ وَلِلْمُقِيمِ يَوْمٌ وَلَيْلَةٌ»
