Faith has over seventy branches, the most excellent of which is the declaration that there is no god but Allah, and the humblest of which is the removal of a bone from the road. And modesty is a branch of faith. (Using translation from Abū Dāʾūd 4676)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ الْإِيمَانُ بِضْعٌ وَسَبْعُونَ بَابًا أَفْضَلُهَا لَا إِلَهَ إِلَّا اللهُ وَأَدْنَاهَا إِمَاطَةُ الْعَظْمِ عَنِ الطَّرِيقِوَالْحَيَاءُ شُعْبَةٌ مِنَ الْإِيمَانِ
