Al-Lu'lu Wal-Marjan 1130 — The Book of Al-Jihad (Fighting for Allâh's Cause)

Abû Burda Narrated from:

The Prophet ﷺ sent his father, (Abû Mûsa) and Mu'âdh to Yemen and said to both of them, "Facilitate things for the people (be kind and lenient) and do not make things difficult (for people), and give good tidings, and do not repulse them (i.e. make them to run away from Islâm), and both of you should obey each other." ( Sahîh Al-Bukhâri, Hadîth No. 632, Vol. 5 )
