[16].Surah An-Nahl [The Bees] : Ayat5-7

Ayat 5. And the cattle, He has created them for you; in them there is warmth (warm clothing), and numerous benefits, and of them you eat.

Ayat 6. And wherein is beauty for you, when you bring them home in the evening, and as you lead them forth to pasture in the morning.

Ayat 7. And they carry your loads to a land that you could not reach except with great trouble to yourselves. Truly, your Lord is full of Kindness, Most Merciful.

Hazrat Aishah (May Allah be pleased with him) reported: The Messenger of Allah  [SAWW](PBUH) said, "Allah is Forbearer and He loves forbearance, and rewards for forbearance while He does not reward severity, and does not give for any thing besides it (forbearance).'' [Muslim Book 32, Chapter 21, Hadith # 6273] 

Mildness is the opposite of harshness. Allah enjoins softness and dislikes stiffness in human relations. Allah assures of reward for gentle behaviour in society, not for unkindness or anything like that. However, inflexibility is preferred to flexibility when there arises a question of religious matters and the limits set by Allah.

Lesson : as mentioned above in Surah An-Nahl Ayat 7.Truly, your Lord is full of Kindness, Most Merciful.
