“She said: “Alas for me! shall I bear a child, seeing I am an old woman, and my husband here is an old man? That would indeed be a wonderful thing!” They said: “Dost thou wonder at Allah’s decree? The grace of Allah and His blessings on you, O ye people of the house!
for He is indeed worthy of all praise, FULL OF ALL GLORY !”
