Abaan bin Salim رحمه الله:

‏كلمة حكمة لك من أخيك خير لك من مال يعطيك، لأن المال يُطغيك، والكلمة تهديك

“A word of wisdom for you from your brother is better for you than money that he gives you, because money leads you to excessiveness, and a word (of wisdom) will guide you.”

‏بهجة المجالس وأنس المجالس لابن عبد البر رحمه الله

A man said to Imām Ahmed رحمه الله:

“How are you Abu Abdillah?

He رحمه الله replied: I am in good health.

So, the man said: (I heard) you had a fever last night

Imām Ahmed رحمه الله said: If I said to you I am in good health, then it suffices for you. Don’t lead me to what I dislike.” (Complaining to the creation and reducing his reward for his Sabr)

[مختصر منهاج القاصدين ٢٧٤]

قيل للإمام أحمدَ بنِ حنبل:

It was said to al-Imam Ahmad b. Hanbal رحمه الله :

الرجلُ يدخل المسجدَ فيرى قومًا فيُحسِّن صلاتَه، أيكون رياءً ؟

A man enters the masjid, and sees people around so he beautifies his salah, is this Riya'?

قال: لا، تلك بركةُ المسلم على المسلم!

He said: No, that is the blessing of a Muslim upon another Muslim

Ibn al-Qayyim رحمه الله:

“Abstaining from lowering one’s gaze engraves the images (of the one who is seen) in the heart, and the heart is like the Ka'bah, and surely it will not be satisfied with idols.”

The Prophet ‎[ﷺ] said,

“No one who enters Paradise would like to return to the world, even if he could have everything on earth, except for the martyr. He will wish to return to the world and be killed ten more times due to the generous reward he sees.”

اَللّٰهُمَّ أَعِنِّيْ عَلَىٰ ذِكْرِكَ وَشُكْرِكَ وَحُسْنِ عِبَادَتِكَ.

Allāhumma aʿinnī ʿalā dhikrika wa shukrika wa ḥusni ʿibādatik.

O Allah, help me in remembering You, in being grateful to You, and in worshipping You in an excellent manner.

Muʿādh b. Jabal (‎رضي الله عنه) reported that the Messenger of Allah ﷺ took him by the hand and he said,

“O Muʿādh, I swear by Allah that I love you. I swear by Allah that I love you. O Muʿādh, I advise you:

Never miss out on saying [the above] after every salah.

[Abu Dawud 1522]

Imām Ibn al-Qayyim (رحمه الله) said:

“Thinking about what does not matter to you is the door of every evil.”

[Al-Fawā’id, 1/175]

Abu Huraira reported Nabi (ﷺ) as saying:

”Allah is more pleased with the repentance of His servant when he turns penitently towards Him than one of you would be on finding the lost camel.“

"If any of you knew the reality of the hellfire, he would scream until his voice broke, and he would pray until his spine fractures."
