سُنَّةَ اللّٰهِ فِی الَّذِیْنَ خَلَوْا مِنْ قَبْلُ وَلَنْ تَجِدَ لِسُنَّةِ اللّٰهِ تَبْدِیْلًا ۟

Sunnatal laahi fil lazeena khalaw min qablu wa lan tajida lisunnatil laahi tabdeelaa

“(Such was) the practice (approved) of Allah among those who lived aforetime: No change wilt thou find in the practice (approved) of Allah.”
