[Machine] The Messenger of Allah ﷺ passed by Abu Isra'il while he was standing in the sun. He said, "What is the matter with him?" They said, "O Messenger of Allah, he has vowed not to speak, not to sit, and to observe fasting." So he said, "Tell him to speak, seek shade, sit and complete his fast, and he is not required to offer expiation."
مَرَّ رَسُولُ اللهِ ﷺ عَلَى أَبِي إِسْرَائِيلَ وَهُوَ قَائِمٌ فِي الشَّمْسِ فَقَالَ «مَا بَالُ هَذَا؟» قَالُوا يَا رَسُولَ اللهِ نَذَرَ أَنْ لَا يَتَكَلَّمَ وَلَا يَقْعُدَ وَأَنْ يَصُومَ فَقَالَ «مُرْهُ فَلْيَتَكَلَّمْ وَلْيَسْتَظِلَّ وَلْيَقْعُدْ وَلْيُتِمَّ وَلَمْ يَأْمُرْهُ بِالْكَفَّارَةِ»
