A good deed is beneficial even it is little, and even a small sin is destructive. A hadith states: “Sometimes a person says something which pleases Allah. Yet, he does not pay attention to it (i.e. some statements are considered absolutely unimportant by man), but Allah raises many of his ranks due to that statement. Sometimes a person says something which displeases Allah, yet he is not mindful that he will fall into Hellfire due to that statement. (Ṣaḥīḥ Al-Bukhārī: 6478)
