The Prophet (Allah bless him and give him peace) said, “Whoever possesses the following three qualities will have the sweetness of faith:
1. The one to whom Allah and His Apostle becomes dearer than anything else.
2. Who loves a person and he loves him only for Allah’s sake.
3. Who hates to revert to Atheism (disbelief) as he hates to be thrown into the fire.” (Bukhari, Volume 1, Book 2, Number 16)
Explaning it Sayyidi wa sanadi Shaykh Mawlana Mohammad TAqi Usmani (may Allah preserve him) said,
“What is meant by sweetness of faith (here)?
Literally sweetness means a sugary taste. However, here this taste of sugar and molasses is not implied. It means that the hardship that usually accompany the obligations of faith become pleasurable. To endure these difficulties is delightful and enjoyable. The pleasure, joy and satisfaction achieved in fulfilling these commandments of faith ordered by Allah exceeds all worldly pleasures and enjoyments. This state is given by Allah to His chosen servants. And it is this condition that is called sweetness or pleasure of faith (eman).

May Allah, Most High give this to us all,
even though we do not deserve it at all.
