Surah Al-Bakarah, Ayah-196, Holy Quran

back home, these are ten days complete. This Command is for him who is not the dweller of Mecca and
remains fearing to Allah and knows that the torment of Allah is severe...

And The Most Beloved Things With Most Beloved Things With Which My Salves Come Nearer To Me, is What I've Enjoined Upon Him; And My Slave Keeps Coming Closer To Me Through Performing Nawafil (Praying or Doing Extra Deeds Besides What is Obligatory) Till I Love Him. Then, I Become His Sense Of Hearing With Which He Hears, And His Sense Of Sight With Which He Sees, And His Hands With Which He Grips, And His Legs With Which He Walks; And If He Asks Me, I'll Give Him, & If He Asks My Protection (Refuge), I'll Protect Him; And I Don't Hesitate Anything As I Hesitate To Take The Soul Of The Believer, For He Hates Death & I Hate To Disappoint Him.'"
