Al-Asr

There is no doubt that the end will come, and Allah(SWT) is Al-Haqq, The TRUTH! Have you asked yourself, what have you done in the past week, past month, past year or even in the past decade for most? Have you repented to your Lord like a Slave to his Master should after a sinful act? Or have we simply forgotten how to Fear Him? 

Ponder upon Allah(SWT)'s Majestic words.

By time,

Indeed, mankind is in loss,

Except for those who have believed and done righteous deeds and advised each other to truth and advised each other to patience.

Imam Ash-Shaafi'ee, may Allah the Most High have Mercy on him, said: "If Allah had sent down to His creation no other proof besides this Surah, it would have been sufficient for them."
