“When anyone of you performs prayer, let him put something in front of him. If he cannot find anything then let him put a stick. If he cannot find one, then let him draw a line. Then it will not matter if anything passes in front of him.”
عَنِ النَّبِيِّ ﷺ قَالَ إِذَا صَلَّى أَحَدُكُمْ فَلْيَجْعَلْ تِلْقَاءَ وَجْهِهِ شَيْئًا فَإِنْ لَمْ يَجِدْ فَلْيَنْصِبْ عَصًا فَإِنْ لَمْ يَجِدْ فَلْيَخُطَّ خَطًّا ثُمَّ لاَ يَضُرُّهُ مَا مَرَّ بَيْنَ يَدَيْهِ
