'Amr bin Wāqid said: Yūnus bin Maysarah narrated to us, saying: I heard Mu'āwiyah (may Allāh be pleased with him) say on the pulpit (minbar) of Dimashq (Damascus) said: “Give charity, and none of you must say: ‘I am constrained (or tight fisted),’ for the charity of the one who is constrained is better than the charity of the one who is wealthy.”
'Abdullāh bin 'Umar (may Allāh be pleased with them both) said: “Every bid'ah (religious innovation) is misguidance even if people think it is good.”
Anas bin Mālik (may Allāh be pleased with him) said: “You people do (bad) deeds (commit sins) which seem in your eyes as tiny (minute) than hair while we used to consider those (very deeds) during the life-time of the Prophet (peace and blessings of Allāh be upon him) as destructive sins.”
'Abdullāh bin 'Umar (may Allāh be pleased with them both) said: “In the evening do not expect [to live until] the morning, and in the morning do not expect [to live until] the evening. Take [advantage of] your health before times of sickness, and [take advantage of] your life before your death.”

'Abdullāh bin Mas'ūd (may Allāh be pleased with him) said: “You are in the passage of day and night, your life decreases [by every passing moment] but your deeds are all preserved and death shall come to you all of a sudden. So, whoever planted good is soon to expect the harvest of happiness, and whoever planted evil is soon to expect the harvest of regret.”
Abū Bakr aṣ-Ṣiddīq (may Allāh be pleased with him) said: “Where is the beauty and the handsome? Where are those who were delighted by their youth and good looks?

Hasten and hurry up [to do good deeds] but death is faster.”

Shaykh al-'Uthaymīn (may Allāh have mercy upon him): “Some of the the salaf said: ‘I like to beautify myself for my wife just as I want that she beautifies herself for me.’ This can fall under the ḥadīth: ‘None of you truly believes until he loves for his brother that which he loves for himself.’” [Ṣaḥīḥ al-Bukhārī (13), Ṣaḥīḥ Muslim (45)]
