Sura Yūnus 10:51

أَثُمَّ إِذَا مَا وَقَعَ ءَامَنتُم بِهِۦٓ ءَآلْـَٰٔنَ وَقَدْ كُنتُم بِهِۦ تَسْتَعْجِلُونَ

athumma- idhā mā waqaʿa āmantum bihi ālʾāna wa-qad kuntum bihi tastaʿjilūna

"Would ye then believe in it at last, when it actually cometh to pass? (It will then be said): 'Ah! now? and ye wanted (aforetime) to hasten it on!'

Sura Yūnus 10:84

وَقَالَ مُوسَىٰ يَٰقَوْمِ إِن كُنتُمْ ءَامَنتُم بِٱللَّـهِ فَعَلَيْهِ تَوَكَّلُوٓا۟ إِن كُنتُم مُّسْلِمِينَ

wa-qāla mūsā yā-qawmi in kuntum āmantum billāhi faʿalayhi tawakkalū in kuntum muslimīna

Moses said: "O my people! If ye do (really) believe in Allah, then in Him put your trust if ye submit (your will to His)."
