Al Baqarah 269
Alloh memberikan Hikmat kebijaksanaan (ilmu yang berguna) kepada siapa yang dikehendakiNya dan siapa yang diberikan hikmat itu maka sesungguhnya dia telah diberikan kebaikan yang banyak. Dan tiadalah yang dapat mengambil pengajaran (dan peringatan) melainkan orang-orang yang menggunakan akal fikirannya.

Hadist Nabi :

Pergunakanlah kesempatan lima (perkara) sebelum (datangnya) lima (perkara):

1. Waktu hidupmu sebelum matimu,

2. Waktu sehatmu sebelum sakitmu,

3. Waktu luangmu sebelum sibukmu,

4. Waktu mudamu sebelum tuamu dan

5. Waktu kayamu sebelum kefakiranmu.
