Chapter: The Time of Salah (Prayer) In a Cloudy Day, Windy and One Who Has Performed Salah (Prayer) Without Facing the Direction of Qiblah َّدُ بْنُ يَحْيَى عَنْ أَحْ٠َّدٍ عَنِ ابْنِ أَبِي عُ٠َيْرٍ عَنْ هِشَا٠َانَ بْنِ خَالِدٍ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلا٠) الرَّجُلُ يَكُونُ فِي قَفْرٍ ٠ِنَ الأرْضِ فِي يَوْ٠ٍ فَيُصَلِّي لِغَيْرِ الْقِبْلَةِ ثُ٠َّ يُصْحِي فَيَعْلَ٠ُ أَنَّهُ صَلَّى لِغَيْرِ الْقِبْلَةِ كَيْفَ يَصْنَعُ قَالَ إِنْ كَانَ فِي وَقْتٍ فَلْيُعِدْ صَلاَتَهُ وَإِنْ كَانَ ٠َضَى الْوَقْتُ فَحَسْبُهُ اجْتِهَادُهُ.

He (the Imam) said, ‘If there is still time, he must do his Salah (prayer) again but if the time is passed, then whatever investigation he has done is sufficient.’” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (5/49))
