﴿ لَٰكِنِ ٱلَّذِينَ ٱتَّقَوْا۟ رَبَّهُمْ لَهُمْ غُرَفٌۭ مِّن فَوْقِهَا غُرَفٌۭ مَّبْنِيَّةٌۭ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ ۖ وَعْدَ ٱللَّهِ ۖ لَا يُخْلِفُ ٱللَّهُ ٱلْمِيعَادَ ﴾

“As against this they who of their Sustainer are conscious shall [in the life to come] have man­sions raised upon mansions high, beneath which run­ning waters flow: [this is] God’s promise - [and] never does God fail to fulfill His promise.”

But as for those who fear their Lord and therefore obey Him — for them there will be lofty abodes with other lofty abodes built above them with rivers flowing beneath them that is beneath both the upper and the lower abodes — a promise of God wa‘da’Llāhi in the accusative because of an implied verb governing it. God does not fail the tryst He does not break His promise.
