Tell the truth
Allah says in the Qur’an: O you who believe, fear Allah and be with those who are truthful. (At-Taubah: 119) Among the believers are those who stay true to their promise to Allah. (Al-Ahzab: 23) This is a day when being truthful will benefit the truthful. (Al-Maa’idah: 119)
The Prophet ﷺ said: Be truthful. Truthfulness leads to goodness, and goodness leads to paradise. A person who keeps telling the truth and holding on to it will be written by Allah as a truly honest person. (HR. Al-Bukhari 6094 and Muslim 2607 from Ibnu Mas’ud)
