Brothers and Sisters in Islam. Can you please enlighten me on teachings of the Prophet (saw) and Quran when interacting with an ingrate. Someone who begs you to earn your favor and once they get it, they call you names and ready to walk on you with the same favor or knowledge

Don't look at anyone as an ingrate. How? When you do a favour unto someone, do not expect thanks or gratitude from them. Hope for reward only from your Lord.

Actually, look at all favours you do as storing up good for yourself rather than seeing it as helping others.

“Kind words and forgiving of faults are better than charity followed by injury. And Allah is Rich (Free of all wants) and He is most Forbearing.” ❂

❋ Quran – 2:263 ❋

Surah 76 Verses 1-12

1.Has there [not] come upon man a period of time when he was not a thing [even] mentioned?
2.Indeed, We created man from a sperm-drop mixture that We may try him; and We made him hearing and seeing.
3.Indeed, We guided him to the way, be he grateful or be he ungrateful.
4.Indeed, We have prepared for the disbelievers chains and shackles and a blaze.
5.Indeed, the righteous will drink from a cup [of wine] whose mixture is of Kafur,
6.A spring of which the [righteous] servants of Allah will drink; they will make it gush forth in force [and abundance].
7.They [are those who] fulfill [their] vows and fear a Day whose evil will be widespread.
8.And they give food in spite of love for it to the needy, the orphan, and the captive,
9.[Saying], "We feed you only for the countenance of Allah . We wish not from you reward or gratitude.
10.Indeed, We fear from our Lord a Day austere and distressful."
11.So Allah will protect them from the evil of that Day and give them radiance and happiness
12.And will reward them for what they patiently endured [with] a garden [in Paradise] and silk [garments].

“Do a good deed,
Throw it into the sea,
If the fish don’t know,
The Creator will.”

Remember that any good deed you do, your creator has a record for it. Its between you and Allah no one else.

"And with Him are the keys of the unseen; none knows them except Him. And He knows what is on the land and in the sea. Not a leaf falls but that He knows it. And no grain is there within the darknesses of the earth and no moist or dry [thing] but that it is [written] in a clear record." [Qur'an 6:59]

we do good for Allah's sake.if anyone is grateful,gratefulness to man is a sign of gratefulness to God who provides everything for man.
