And if they deny you - then already have those before them (35:25)

﴿وَإِن يُكَذِّبُوكَ فَقَدْ كَذَّبَ الَّذِينَ مِن قَبْلِهِمْ جَاءَتْهُمْ رُسُلُهُم بِالْبَيِّنَاتِ وَبِالزُّبُرِ وَبِالْكِتَابِ الْمُنِيرِ﴾
[ فاطر: 25]

35:25 And if they deny you - then already have those before them denied. Their messengers came to them with clear proofs and written ordinances and with the enlightening Scripture.

And if your people deny you, O Messenger, be patient, because you are not the first Messenger whose people denied him, as the nations before them denied their messengers, such as Aad, Thamud and the people of Lot.
Their messengers came to them with clear evidences and overwhelming miracles which prove their truthfulness, and their messengers came to them with scrolls and with the Scripture which is enlightening for one who ponders over it and contemplates it.

And if they belie you, those before them also belied. Their Messengers came to them with clear signs, and with the Scriptures, and the book giving light.
