20 Preface لٰكِنِ الَّذينَ اتَّقَوا رَبَّهُم لَهُم غُرَفٌ مِن فَوقِها غُرَفٌ مَبنِيَّةٌ تَجري مِن تَحتِهَا الأَنهارُ ۖ وَعدَ اللَّهِ ۖ لا يُخلِفُ اللَّهُ الميعادَYusuf AliBut it is for those who fear their Lord. That lofty mansions,1 one above another, have been built: beneath them flow rivers (of delight): (such is) the Promise of God. never doth God fail in (His) promise.2Cf. 29:58, and 34:37. The idea of heaven here is that of a Home of sublimity and beauty, with a picturesque outlook, such as we would describe in this life by the type of a palace by gently-flowing streams. The mansions will also suggest generous space and architectural beauty, tiers upon tiers piled one upon another.Mi'ad: the time, place and manner of the fulfilment of a Promise. God’s promise will be fulfilled in all particulars better than we can possibly imagine.
