Assalamualaikum
Yeah sis. There are some relatives who are a bit selfish but Allah made them so. I am not so much good at giving advice but I just wanted to reply you I have seen your previous posts. You are not being selfish it's ok :). You are just bring tested by Allah with your relations. Here are some comforting ahadith and verses of Quran.
Narrated Abdullah bin 'Amr (RA):
The Prophet (SAW) said, "Al-Wasil is not the one who recompenses the good done to him by his relatives, but Al-Wasil is the one who keeps good relations with those relatives who had severed the bondof kinship with him."
Bukhari Vol. 8 : No. 20
Narrated by Abu Huraira (RA):
The Prophet (SAW) said, "Beware of suspicion, for suspicion is the worst of false tales; and do not look for the others faults and do not spy, and do not be jealous of one another, and do not desert (cut your relation with) one another, and do not hate one another; and O Allah's worshippers! Be brothers (as Allah has ordered you!")
Bukhari Vol. 8 : No. 90
'Be not sad, surely Allah is with us.'- (Qur’an 9:40)
'So do not become weak, nor be sad'- (Qur’an 3:139)
'O you who believe! Seek help in patience and the prayer.'-(Qur’an 2:153)
'Verily,with hardship there is relief'- (Qur’an 94:6)
'Verily,in the remembrance of Allah do hearts find rest.-'(Qur’an 13:28)
'Remember Me; I will remember you'- (Quran 2:152)
“And there is no sin on you concerning that in which you made a mistake, except in regard to what your hearts deliberately intend”
[al-Ahzaab 33:5]
Allah has promised, to those among you who believe and work righteous deeds, that He will, of a surety, grant them in the land, inheritance (of power), as He granted it to those before them; that He will establish in authority their religion - the one which He has chosen for them; and that He will change (their state), after the fear in which they (lived), to one of security and peace: ´They will worship Me (alone) and not associate aught with Me. ´If any do reject Faith after this, they are rebellious and wicked.
(An-Noor: verse 55)
And whatever strikes you of disaster - it is for what your hands have earned; but He pardons much.
(Ash-Shura: Verse 30)
Whatever you have will end, but what Allah has is lasting. And We will surely give those who were patient their reward according to the best of what they used to do.(Surah Taha 20:96)
No matter how bad life is treating you right now, there is always someone who is worse off than you. Don't surround yourself in sorrow.Say Alhamduillah !
Maybe you have read this earlier. I feel it's really helpful.
People are often unreasonable, illogical and self centred;
Forgive them anyway
If you are kind, people may accuse you of selfish, ulterior motives;
Be kind anyway.
If you are successful, you will win some false friends and some true enemies;
Succeed anyway.
If you are honest and frank, people may cheat you;
Be honest and frank anyway.
What you spend years building, someone could destroy overnight;
Build anyway.
If you find serenity and happiness, they may be jealous;
Be happy anyway.
The good you do today, people will forget tomorrow;
Do good anyway.
Give the world the best you have, and it may never be enough;
Give the world the best you've got anyway.
You see, in the final analysis, it is between you and God;
It never was between you and them anyway.
No matter how good or bad you have it, wake up each day thankful for your life. Someone somewhere else is fighting to survive.
Also if you have time read this article.
