يَد hand in Arabic

إن وجدتَ قلبَك ألينَ، ولسانَك أصدقَ، ويَدَك أعدلَ، فذلك ثمرُه

If you find your heart softer, your tongue more truthful, and your hand more just, that is its fruit.

وَيَدَكَ and your hand

From Remembrance That Reshapes the Heart

ومن بايع إماماً فأعطاه صفقة يده، وثمرة قلبه، فليطعه إن استطاع،

And whoever gives allegiance to an Imam, giving him a handshake and sincerity of his heart, let him obey him if he is able,

يَدِهِ of his hand

This is 'hand' with 'his' attached, the owner-half of 'clasp of his hand', its possessor-form supplying the 'of'. The suffix points back to the pledger; the pairing names the physical handshake.

From A Prophet Warns His People

فإن استطاع أن لا يغضب فهو الكامل، وإلا فليمسك لسانه ويده

If he can avoid getting angry, he is complete; otherwise, let him restrain his tongue and his hand.

وَيَدَهُ and his hand

The joined 'and' plus a noun 'hand' with an attached 'his' fused on, coordinated as a second object of 'restrain': and his hand. The suffix carries the possessor; standing for his actions, it too must be held back.

From Restraining Anger

وَقَوْلُهُمْ خَيْرُ الْأُمُورِ أَوْسَاطُهَا، مَذْكُورٌ فِي قَوْلِهِ تَعَالَى وَلَا تَجْعَلْ يَدَكَ مَغْلُولَةً إِلَى عُنُقِكَ وَلَا تَبْسُطْهَا كُلَّ الْبَسْطِ

And their saying: 'The best of matters is its middle' is mentioned in His saying: 'And do not make your hand chained to your neck, nor open it completely.'

يَدَكَ your hand

This is 'hand' with the attached 'your' (male singular), a possessive, the hand belonging to the addressee. It is the first object of 'make', the thing being told not to be put in a certain state. The suffix marks it as the listener's own hand.

From When Scripture Answers Proverbs

وَأَشَارَ بِيَدِهِ إِلَى لِسَانه وَقَالَ تَدْمَع الْعين ويحزن الْقلب وَلَا نقُول إِلَّا مَا يرضى الرب

And he pointed with his hand to his tongue and said, 'The eye sheds tears, and the heart grieves, but we do not say except what pleases the Lord.'

بِيَدِهِ with his hand

A preposition 'with/by' carrying a noun 'hand' with 'his' attached, 'with his hand'. One word bundles preposition, noun, and possessor; it marks the instrument of the pointing.

From Patience in Hard Times

ثم قال والذي نفسي بيده إن ما بين المصراعين من مصاريع الجنة كما بين مكة وهجر، أو كما بين مكة وبصرى

Then he said: "By the One in whose hand is my soul, indeed, the distance between the two panels of the gates of Paradise is as between Mecca and Hajar, or as between Mecca and Busra."

بِيَدِهِ in whose hand is

The prefix 'bi-' marks 'in (the) hand' and '-hi' makes it 'His hand', pointing back to the One sworn by; the noun sits in the form that prefix governs. One word holds 'in', 'hand' and 'His'.

From The Prophet's Intercession

وذلك يشترك فيه أهل اليد والقدرة وأهل العلم والكلام،

This includes both people of power and capability and people of knowledge and speech.

الْيَدِ power

The 'the' makes this noun definite, and it owns the preceding 'people of', giving 'the people of strength' (literally 'of the hand'). As the owner in the 'of' pairing it carries the genitive ending.

From Obedience to God and Authority

فلبثت والقدح على يدى أنتظر استيقاظهما حتى برق الفجر والصبية يتضاغون عند قدمى فاستيقظا فشربا غبوقهما

So I waited with the vessel in my hand until dawn broke, and the children were crying at my feet. They then awoke and drank their evening drink.

يَدِي my hand

This noun carries the possessor -i ('my') and sits in the 'of' (genitive) ending under the preposition before it. The suffix folds owner and owned into one word, 'my hand', marking where the vessel rested.
