7. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn abu Nasr from al-Husayn ibn Khalid and Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Uthman al-Khazzaz from a man from al-Husayn ibn Khalid who has said the following: “I once asked abu al-Hassan , about mahr (dower) according to Sunnah and how it has become five hundred. He (the Imam) said, ‘Allah, most Blessed, most High, has made obligatory upon Himself that if any believing person says one hundred times Takbir (Allah is great beyond description), one hundred times, Tasbih (Allah is free of all defects), one hundred times, Tahmid, (all praise belongs to Allah), one hundred times, Tahlil, (no one deserves worship except Allah) one hundred times and one hundred times, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, and then says, ‘O Allah pair me up with Hur al-‘In .’ Allah pairs him up with a Hawra’ al-‘In and makes this (things he has said) as mahr (dower). Then Allah, most Majestic, most Glorious, sent revelation to His Holy prophet, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, to set mahr (dower) for the believing women at five hundred dirham. The Messenger of Allah followed the instruction and if any believing man proposes marriage to his brother in belief for his graceful daughter with five hundred dirham as mahr (dower) and he does not agree, he has caused a suspension and he will not deserve from Allah, most Majestic, most Glorious, to pair him with Hur al-‘In.’”
