"The Messenger of Allah said to me: 'Have Taqwa of Allah wherever you are, and follow an evil deed with a good one to wipe it out, and treat the people with good behavior." (Using translation from Tirmidhī 1987)
"اذْكُرِ الله، حيثما كُنتَ، وخالقَ النَّاسَ بخلُقٍ حسنٍ، وأتبعِ السَّيئةَ الحسنةَ تَمْحُها".
