Sheikh Shanqeeti said:
If your Iman drops and you become lazy with worship then repeat this du'a:
اللَّهُمَّ لا تَجْعَلْنِي شَقِيًّا وَلا مَحْرُومًا
“O Allāhﷻ do not make me wretched or deprived [of good].”
Protect yourself from the punishment of Allah:
The Prophet, sallallaahu 'alayhi wa sallam, said: “Protect yourselves from the Fire, by giving in charity even half a date.”
[Al-Bukhari]
لا تحقرن من المعروف شيئاً، ولو أن تلقى أخاك بوجه طلق (رواه مسلم)
“Let not any of you belittle or look down upon a good deed, even if it be that you smile in the face of your brother.” (Muslim)
