Hadith - Qudsi 22

Let not any one of you belittle himself. They said: O Messenger of Allah, how can any one of us belittle himself? He said: He finds a matter concerning Allah about which he should say something, and he does not say [it], so Allah (mighty and sublime be He) says to him on the Day of Resurrection: What prevented you from saying something about such-and-such and such-and-such? He say: [It was] out of fear of people. Then He says: Rather it is I whom you should more properly fear.

Hadith - Al-Tirmidhi #5083, Narrated AbuDharr

Allah's Messenger said to him, "Fear Allah wherever you are; if you follow an evil deed with a good one you will obliterate it; and deal with people with a good disposition."

Ahmad, Tirmidhi and Darimi

Hadith - Al-Tirmidhi #5140, Narrated Hudhayfah

The Prophet said, "By Him in Whose hand my soul is, you must enjoin what is reputable and forbid what is disreputable, or Allah will certainly soon send punishment from Himself to you. Then you will make supplication and not receive an answer."

Hadith - Al-Tirmidhi #5142, Narrated AbuBakr as-Siddiq

You people recite this verse, "You who believe, care for yourselves; he who goes astray cannot harm you when you are rightly guided." I heard Allah's Messenger say, "When people see something objectionable and do not change it, Allah will soon include them all in His punishment."

Who do you fear? Mankind? or Allah swt?

The Noble Qur'an At-Taubah 9:13

Will you not fight a people who have violated their oaths (pagans of Makkah) and intended to expel the Messenger, while they did attack you first? Do you fear them? Allah has more right that you should fear Him, if you are believers.

Hadith - Al-Tirmidhi #5306, Narrated AbuDharr -Ahmad, Ibn Majah and Darimi transmitted it.

Allah's Messenger said, he knew a verse which would suffice men if they would but apply it, "For him who fears Allah He will appoint a way out and He will give him provision from an unimagined source.'"

Tears of Fear
