Sura al-Baqara 2:261

مَّثَلُ ٱلَّذِينَ يُنفِقُونَ أَمْوَٰلَهُمْ فِى سَبِيلِ ٱللَّـهِ كَمَثَلِ حَبَّةٍ أَنۢبَتَتْ سَبْعَ سَنَابِلَ فِى كُلِّ سُنۢبُلَةٍ مِّا۟ئَةُ حَبَّةٍ وَٱللَّـهُ يُضَٰعِفُ لِمَن يَشَآءُ وَٱللَّـهُ وَٰسِعٌ عَلِيمٌ

mathalu lladhīna yunfiqūna amwālahum fī sabīli allāhi ka-mathali ḥabbatin anbatat sabʿa sanābila fī kulli sunbulatin miatu ḥabbatin wallāhu yuḍāʿifu li-man yashāʾu wallāhu wāsiʿun ʿalīmun

The parable of those who spend their substance in the way of Allah is that of a grain of corn: it groweth seven ears, and each ear Hath a hundred grains. Allah giveth manifold increase to whom He pleaseth: And Allah careth for all and He knoweth all things.

Sura al-Anʿām 6:59

وَعِندَهُۥ مَفَاتِحُ ٱلْغَيْبِ لَا يَعْلَمُهَآ إِلَّا هُوَ وَيَعْلَمُ مَا فِى ٱلْبَرِّ وَٱلْبَحْرِ وَمَا تَسْقُطُ مِن وَرَقَةٍ إِلَّا يَعْلَمُهَا وَلَا حَبَّةٍ فِى ظُلُمَٰتِ ٱلْأَرْضِ وَلَا رَطْبٍ وَلَا يَابِسٍ إِلَّا فِى كِتَٰبٍ مُّبِينٍ

waʿindahu mafātiḥu l-ghaybi lā yaʿlamuhā illā huwa wa-yaʿlamu mā fī l-barri wa-l-baḥri wa-mā tasquṭu min waraqatin illā yaʿlamuhā wa-lā ḥabbatin fī ẓulumāti l-arḍi wa-lā raṭbin wa-lā yābisin illā fī kitābin mubīnin

With Him are the keys of the unseen, the treasures that none knoweth but He. He knoweth whatever there is on the earth and in the sea. Not a leaf doth fall but with His knowledge: there is not a grain in the darkness (or depths) of the earth, nor anything fresh or dry (green or withered), but is (inscribed) in a record clear (to those who can read).

Sura al-Anbiyāʾ 21:47

وَنَضَعُ ٱلْمَوَٰزِينَ ٱلْقِسْطَ لِيَوْمِ ٱلْقِيَٰمَةِ فَلَا تُظْلَمُ نَفْسٌ شَيْـًٔا وَإِن كَانَ مِثْقَالَ حَبَّةٍ مِّنْ خَرْدَلٍ أَتَيْنَا بِهَا وَكَفَىٰ بِنَا حَٰسِبِينَ

wa-naḍaʿu l-mawāzīna l-qisṭa li-yawmi l-qiyāmati fa-lā tuẓlamu nafsun shayʾan wa-in kāna mithqāla ḥabbatin min khardalin ataynā bihā wa-kafā binā ḥāsibīna

We shall set up scales of justice for the Day of Judgment, so that not a soul will be dealt with unjustly in the least, and if there be (no more than) the weight of a mustard seed, We will bring it (to account): and enough are We to take account.

Sura Luqmān 31:16

يَٰبُنَىَّ إِنَّهَآ إِن تَكُ مِثْقَالَ حَبَّةٍ مِّنْ خَرْدَلٍ فَتَكُن فِى صَخْرَةٍ أَوْ فِى ٱلسَّمَٰوَٰتِ أَوْ فِى ٱلْأَرْضِ يَأْتِ بِهَا ٱللَّـهُ إِنَّ ٱللَّـهَ لَطِيفٌ خَبِيرٌ

yā-bunayya innahā in taku mithqāla ḥabbatin min khardalin fa-takun fī ṣakhratin aw fī l-samāwāti aw fī l-arḍi yaʾti bihā allāhu inna allāha laṭīfun khabīrun

"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).
