Surah Luqman (Luqman), Verse 16

یٰبُنَیَّ اِنَّهَاۤ اِنْ تَكُ مِثْقَالَ حَبَّةٍ مِّنْ خَرْدَلٍ فَتَكُنْ فِیْ صَخْرَةٍ اَوْ فِی السَّمٰوٰتِ اَوْ فِی الْاَرْضِ یَاْتِ بِهَا اللّٰهُ اِنَّ اللّٰهَ لَطِیْفٌ خَبِیْرٌ ۟

Ya bunaiya innahaaa in taku misqaala habbatim min khardalin fatakun fee sakhratin aw fis samaawaati aw fil ardi yaati bi Allah; innal laaha lateefun Khabeer

“"O my son!" (said Luqman), "If there be (but) the weight of a mustard-seed and it were (hidden) in a rock, or (anywhere) in the heavens or on earth, Allah will bring it forth: for Allah understands the finest mysteries, (and) is well-acquainted (with them).”
