م و لwealth

المال · al-māl · wealth, property

• Met in: V1 p7 ¶2a: «العلم خير من المال», "knowledge is better than wealth"; and V1 p7 ¶7b: «فاختار العلم فأعطي المال والملك معه», "he chose knowledge, and was given wealth and kingship with it".
• Dictionary form: مَال (corpus lemma, 86 times in the Quran), plural أَمْوَال, as in ٱلْأَمْوَٰلِ (2:155).
• Pattern: on a root whose middle letter is و: م و ل gives مَال, and the و comes back in the plural أَمْوَال.
• Meaning here: Wealth of any kind: money, goods, property. ʿAlī sets it against knowledge point by point: you guard it, it does not guard you; spending shrinks it (V1 p7 ¶2a).

Ibn Faris, Maqāyīs al-Lugha, root مول, vol 5, p 285

الميم والواو واللام كلمة واحدة، هي تمول الرجل: اتخذ مالا، ومال يمال: كثر ماله

One word: tamawwala, a man acquired wealth; and māla yamālu, his wealth grew.

Quran

86 words from this root (Quranic Arabic Corpus), all مَال (wealth).

ٱلْمَالُ وَٱلْبَنُونَ زِينَةُ ٱلْحَيَوٰةِ ٱلدُّنْيَا وَٱلْبَٰقِيَٰتُ ٱلصَّٰلِحَٰتُ خَيْرٌ عِندَ رَبِّكَ ثَوَابًا وَخَيْرٌ أَمَلًا

Wealth and children are [but] adornment of the worldly life. But the enduring good deeds are better to your Lord for reward and better for [one's] hope.

Surah Al-Kahf (18), ayah 46 · Saheeh International

Why this ayah: «ٱلْمَالُ وَٱلْبَنُونَ زِينَةُ ٱلْحَيَوٰةِ ٱلدُّنْيَا», "Wealth and children are [but] adornment of the worldly life": wealth as adornment, as in the father's letter on V1 p8 ¶11a, where knowledge is the adornment.
