[16].Surah An-Nahl [The Bees] : Ayat 68-69

Ayat 68. And your Lord inspired the bee, saying: "Take you habitations in the mountains and in the trees and in what they erect.

Ayat 69. "Then, eat of all fruits, and follow the ways of your Lord made easy (for you)." There comes forth from their bellies, a drink of varying colour wherein is healing for men. Verily, in this is indeed a sign for people who think. 

Hazrat Abdullah bin Amr bin Al-Aas (May Allah be pleased with him) reported: We were repairing our thatchy hut when Messenger of Allah  [SAWW](PBUH) passed by and asked us, "What are you doing?'' We said, "The thatch had gone weak and we are repairing it.'' He  [SAWW](PBUH) said, "I see the sure thing (death) approaching sooner than this.'' [Tirmidhi Hadith # 2335]. 

Lesson : as mentioned above in Surah An-Nahl Ayat 68. Verily, in this is indeed a sign for people who think. The word "Khuss'' means a hut or a house which is made of wood and reed/bamboo and plastered with mud. The Hadith reminds us to be mindful of death at all times and be certain that there is nothing nearer to us than it. It also tells us that we should not engage in those worldly things which are bound to make us forget about our appointed term in this world.
