فَوَرَبِّ السَّمَاء وَالْأَرْضِ إِنَّهُ لَحَقٌّ مِّثْلَ مَا أَنَّكُمْ تَنطِقُونَ
“By the Lord of the heavens and the earth, verily it is certainly the truth, just as you speak”
Imam Sajjad (as) explained the verse, “Verily it is certainly the truth”, by saying that it refers to the rising of the Qaem (as).
(He explained) that the following verse was also revealed about the Qaem (as), “Allah has promised to appoint those of you who believe and do good deeds, successors in earth, as He had appointed those before them, and He shall certainly establish their religion which He has chosen for them, and He will give them in exchange security after their fear” (Chapter 24 verse 55) (Taweel Al Ayat Al Zahirah page 596)
