Imam Ibn al-Jawzi (may Allah have mercy upon him) said:
“Surely the Salaf used to dislike complaining to the creation. Complaining, even though there is comfort in it, indicates weakness and humiliation. Patience from it is evidence of strength and honor” [at-Thabaat ‘indal-Mamaat (1/55)]
Shaikhul Islaam Ibn Taymiyyah (may Allah have mercy upon him) said: “Verily complaints should be directed towards Allah, the Exalted as the pious servant [Ya’qub] said: “I only complain of my grief and sorrow to Allah [12:86]” [Minhaaj us-Sunnah (4/244)]
Is Complaining to Others Haram?
Shaikhul-Islaam Ibn Taymiyyah (may Allah have mercy upon him) said: “If he complains to others due to what is in complaining of comfort, just as one afflicted with a calamity complains about his calamity to the people without intending to know what will benefit him nor seeking aid in disobedience, then this decreases his patience. However, it is not absolutely sinful except if it is accompanied with that which is unlawful, like one who is afflicted and is discontent [with the calamity]” [Majmoo’ al-Fatawa (14/463)]
