And (recall the time) when Abraham said, `My Lord! show me how You give life to the dead.' (The Lord) said, `Do you not believe (that I can)?' He said, `Yes I do, but (I ask this) that my mind may be at peace.' (The Lord) said, `Take four birds and make them attached to you, then put them each on a separate hill, then call them, they will come to you swiftly. And know that Allâh is All-Mighty, All-Wise.'
