Sayyidina Abdur Rehman bin abi Qerad (Allah be pleased with him) narrates that one day the Prophet (Allah bless him and give him peace) performed wudhu. The blessed Companions (Allah be pleased with them) took that water and rubbed it on their body and faces.

The Prophet (Allah bless him and give him peace) inquired, ‘What makes you do this and what emotion drives it?’

They replied,’The love of Allah and His Prophet (Allah bless him and give him peace).’

On hearing this answer the Prophet (Allah bless him and give him peace) said, ‘An individual who desires and aspires to really love Allah and His Prophet (Allah bless him and give him peace) and that Allah and His Prophet (Allah bless him and give him peace) love him then he should always speak the truth, safely return the things placed in his trust without a bit of embezzlement and treat his neighbor kindly.’
