قَوْلُهُ تَعَالَى: {وَلَا تَجْهَرْ بِصَلَاتِكَ} [الإسراء: 110]
(regarding): 'Neither say your, prayer aloud, nor say it in a low tone.' (17.110) This Verse was revealed while Messenger of Allah ﷺ was hiding himself in Mecca. When he prayed with his companions, he used to raise his voice with the recitation of Qur'an, and if the pagans happened to hear him, they would abuse the Qur'an, the One who revealed it and the one who brought it. Therefore Allah said to His Prophet : 'Neither say your prayer aloud.' (17.110) i.e. do not recite aloud lest the pagans should hear you, but follow a way between. (Using translation from Bukhārī 4722)
فِي قَوْلِهِ ﷻ {وَلَا تَجْهَرْ بِصَلَاتِكَ وَلَا تُخَافِتْ بِهَا} [الإسراء 110] قَالَ نَزَلَتْ وَرَسُولُ اللهِ مُخْتَفٍ بِمَكَّةَ فَكَانَ إِذَا صَلَّى بِأَصْحَابِهِ رَفَعَ صَوْتَهُ بِالْقِرَاءَةِ فَإِذَا سَمِعَ الْمُشْرِكُونَ سَبُّوا الْقُرْآنَ وَمَنْ أَنْزَلَهُ وَمَنْ جَاءَ بِهِ فَقَالَ لِنَبِيِّهِ ﷺ {وَلَا تَجْهَرْ بِصَلَاتِكَ} [الإسراء 110] أَيْ بِقِرَاءَتِكَ فَيَسْمَعَ الْمُشْرِكُونَ فَيَسُبُّوا الْقُرْآنَ {وَلَا تُخَافِتْ بِهَا} [الإسراء 110] أَصْحَابَكَ فَلَا يَسْمَعُونَ {وَابْتَغِ بَيْنَ ذَلِكَ سَبِيلًا} [الإسراء 110]
