If you fear a person because they may block your work, or you befriend someone only so they can help you get things done, then listen to this hadith.
Ibn 'Abbas narrated:
"I was behind the Prophet(s.a.w) one day when he said: 'O boy! I will teach you a statement: Be mindful of Allah and He will protect you. Be mindful of Allah and you will find Him before you. When you ask, ask Allah, and when you seek aid, seek Allah's aid. Know that
if the entire creation were to gather together to do something to benefit you- you would never get any benefit except that Allah had written for you. And if they were to gather to do something to harm you- you would never be harmed except that Allah had written for you. The pens are lifted and the pages are dried.'"
[Jami` at-Tirmidhi 2516]
No one can give benefit or harm except the will of Allah, Allah alone has the power to give blessings and hurt.
If God touches you with harm, there is no one to remove it but Him. And if He intends goodness for you, none can withhold his grace... [Quran 10 : 107]
Say, “I have no power to benefit or protect myself, except by the Will of Allah... [Quran 7 : 188]
Hamare halath hamare iqtiyar mein nahi hain, yaqeen rakhen jis ke iqtiyar mein hai wo “Ala kulli shayin qadeer hai” [Indeed, Allah has power over all things].
If you are a true believer, this above one hadith is enough to kill your fear in anyone other than Allah. So please my brothers and sisters in Islam, keep your hope and fear only on Allah, not in people or his creatures. Indeed true believer does not keep hope or fear other than Allah.
Quran says: ...Of course, nobody can revise or reverse the decisions (and decrees) of Allah!... [Quran 6 : 34]
If something is written in your fate, surely it will happen, no one can stop it. If something is not written in your fate, surely it will not happen. So please live your life in peace, don't fill your mind with worry and anxiety.
