Holy Qur’an 3:200
يا أَيُّهَا الَّذينَ آمَنُوا اصبِروا وَصابِروا وَرابِطوا وَاتَّقُوا اللَّـهَ لَعَلَّكُم تُفلِحونَ
O you who believe! Persevere in patience and constancy. Vie in such perseverance, strengthen each other and be regardful of Allah that ye may prosper.
Sahih Muslim, Hadith
On the authority of Tamim Al-Dari that the Prophet, sallallahu ‘alayhi wasallam, said: Religion is nasihah.” We said: “To whom?” The Prophet, sallallahu ‘alayhi wasallam, said: “To Allah and His Book, and His messenger, and to the leaders of the Muslims and their common folk.”
