عَنْ أَبِي الدَّرْدَاءِ رَضِيَ اللَّهُ عَنْهُ مَرْفُوعًا: ((يَا أَيُّهَا النَّاسُ! إِيَّاكُمْ وَالْإِلْتِفَاتَ فَإِنَّهُ لَا صَلَاةَ لِلْمُلْتَفِتِ، فَإِنْ غُلِبْتُمْ فِي التَّطَوُّعِ فَلَا تُغْلَبُنَّ فِي الْفَرَائِضِ))
It is narrated from Sayyiduna Abu Darda’ (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) said: “O people! Avoid turning (your face) away, for the one who turns away has no prayer. If you are overcome in voluntary prayers (then you may look), but in any case, do not be overcome in the obligatory prayers.”
