(V.9:119) The Statement of Allâh تعالى : ‘O you who believe! Be afraid of Allâh, and be with those who are true (in words and deeds).’ (V.9:119).
And what is forbidden as regards telling of lies.
a) Narrated ‘Abdullâh رضي الله عنه : The Prophet صلى الله عليه وسلم said, "Truthfulness leads to Al-Birr (righteousness) and Al-Birr (righteousness) leads to Paradise. And a man keeps on telling the truth until he becomes a truthful person. Falsehood leads to Al-Fujûr (i.e. wickedness - evil-doing), and Al-Fujûr leads to the (Hell) Fire, and a man keeps on telling lies until he is written as a liar before Allâh." (Sahih Al-Bukhâri, Vol.8, Hadîth No.116).
b) Narrated Abu Hurairah رضي الله عنه : Allâh’s Messenger صلى الله عليه وسلم said, "The signs of a hypocrite are three: Whenever he speaks, he tells a lie; and whenever he promises, he breaks his promise; and whenever he is entrusted, he betrays (proves to be dishonest)." (Sahih Al-Bukhari, Vol.8, Hadith No.117).
c) Narrated Samurah bin Jundub رضي الله عنه : The Prophet صلى الله عليه وسلم said, "I saw (in a dream), two men came to me." Then the Prophet صلى الله عليه وسلم narrated the story (saying): "They said: The person, the one whose cheek you saw being torn away (from the mouth to the ear) was a liar and used to tell lies and the people would report those lies on his authority till they spread all over the world. So he will be punished like that till the Day of Resurrection." (Sahih Al-Bukhari, Vol.8, Hadith No.118).
(V.9:120) Muhsinûn: Doers of good, i.e. those who perform good deeds totally for Allâh’s sake only without any show-off or to gain praise or fame, etc., and they do them in accordance with the Sunnah (legal ways) of Allâh’s Messenger, Muhammad صلى الله عليه وسلم.
(V.9:121)
a) Islâm demolishes all the previous evil deeds and so do migration (for Allâh’s sake) and Hajj (pilgrimage to Makkah). (Sahih Muslim, Vol.1, Chapter 52, Page 18)
b) What is said regarding the superiority of a person who embraces Islâm sincerely.
Narrated Abu Sa‘îd Al-Khudrî رضي الله عنه: Allâh’s Messenger صلى الله عليه وسلم said, "If a person embraces Islâm sincerely, then Allâh shall forgive all his past sins, and after that starts the settlement of accounts: the reward of his good deeds will be ten times to seven hundred times for each good deed, and an evil deed will be recorded as it is unless Allâh forgives it." (Sahih Al-Bukhari, Vol.1, Hadith No. 40A)
Narrated Abu Hurairah رضي الله عنه : Allâh’s Messenger صلى الله عليه وسلم said, "If anyone of you improves (follow strictly) his Islâmic religion, then his good deeds will be rewarded ten times to seven hundred times for each good deed and a bad deed will be recorded as it is." (Sahih Al-Bukhari, Vol.1, Hadith No.4DB)
