There was a person who had performed the nikah of his daughter in the musjid after Asr Salaah. After the nikah was performed, there were just a few dates that were distributed, and the groom did not even wear new clothing for the nikah. Likewise, there were a few other nikahs that took place in a similar manner. In the one nikah, the groom wore his ordinary clothing which he would daily wear for work and his clothing was slightly stained due to work. Seeing this level of simplicity, the people present for the nikah were quite agreeable and had no reservations. Hazrat (rahimahullah) then mentioned:
The nikah of my brother, Mazhar, took place in a similar manner. On the occasion of his nikah, even the old women remarked, “Really, this nikah is full of noor and barakah, and our hearts are enlightened with happiness, despite there not being any elaborate arrangements found.” Subhaanallah! When the nikah was performed in accordance with the Sunnah, then why should noor not be perceived? Furthermore, the more the simplicity of the nikah, the greater will be the noor felt in the heart. The reason for this is that when there is simplicity then there is no opportunity for arguments and quarrelling, and this causes one to have a clear heart (from malice, enmity, etc). On the contrary, when there is a long drawn function and elaborate arrangements, then this leads to arguments and quarrels, and these undoubtedly darken and dull the heart.
