Aal-'Imran - 3:40

قَالَ رَبِّ أَنَّىَ يَكُونُ لِي غُلاَمٌ وَقَدْ بَلَغَنِيَ الْكِبَرُ وَامْرَأَتِي عَاقِرٌ قَالَ كَذَلِكَ اللّهُ يَفْعَلُ مَا يَشَاء
[3:40]
He said: My Lord! when shall there be a son (born) to me, and old age has already come upon me, and my wife is barren? He said: even thus does Allah what He pleases.
He said: "O my Lord! How shall I have son, seeing I am very old, and my wife is barren?" "Thus," was the answer, "Doth Allah accomplish what He willeth."
He said: My Lord! How can I have a son when age hath overtaken me already and my wife is barren? (The angel) answered: So (it will be). Allah doeth what He will.
