سورة الكهف

Imam Sadiq (peace be upon him): إِنَّ الَّذِینَ آمَنُوا وَ عَمِلُوا الصَّالِحاتِ إِنَّا لا نُضِیعُ أَجْرَ مَنْ أَحْسَنَ عَمَلًا [Surely those who believe and do good, We do not waste the reward of him who does a good work], the meaning is the family of Muhammad (peace be upon him and his family).

Imam Ali (peace be upon him): May Allah have mercy on Khabbab; he embraced Islam eagerly, migrated obediently, and lived as a mujahid, and his body was afflicted with illness and his conditions changed, لَنْ یُضِیعَ اللهُ أَجْرَ مَنْ أَحْسَنَ عَمَلا [Allah will never waste the reward of him who does a good work].
