(Addariyath) 51 : 23
فَوَرَبِّ السَّمَاءِ وَالْأَرْضِ إِنَّهُ لَحَقٌّ مِثْلَ مَا أَنَّكُمْ تَنْطِقُونَ
Then by the Lord of the heavens and the earth, indeed It is the Truth as indeed you are talking.
‘Indeed It is the Truth’ has the meaning that just like mankind speaks, the Last of the Universe is also Truth, as well as Adhikr is Truth. See explanation 41: 53; 43: 61.
