Modesty is a part of faith
‘Abdullāh ibn ‘Umar (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said:
"Modesty is a part of faith."
Modesty is a part of faith because the modest person is urged by his modesty to stay away from sins and to perform religious obligations. This is from the results of belief in Allah if the heart is filled with.Faith prevents a person from sins and encourages him to do the obligatory duties. Hence, modesty is similar to faith in status in terms of its eventual effect and benefit upon the servant of Allah.
