In the name of Allah, Most Gracious, Most Merciful.
Abu Hurairah (May Allah be pleased with him): The Prophet (May Allah exalt his mention and protect him from imperfection) said: “Iman has over seventy branches, the uppermost of which is the declaration: ‘None has the right to be worshiped but Allah’; and the least of which is the removal of harmful object from the road, and modesty is a branch of Iman.” (Al-Bukhari and Muslim)
Commentary: This Hadith tells us that from the standpoint of practice, Faith has several stages. It also tells that Faith and practice are inseparable. It also makes evident the importance and excellence of bashfulness because it induces a person to good deeds and deters him from evils.
