At-Tawba 9:91

There is no blame on the weak, the sick, or those who have nothing to spend, as long as they are sincere to Allah and His Messenger. There is no blame on those who do good, and Allah is All-Forgiving, Most Merciful.

There is not upon the weak or upon the ill or upon those who do not find anything to spend any discomfort [i.e., guilt] when they are sincere to Allāh and His Messenger. There is not upon the doers of good any cause [for blame]. And Allāh is Forgiving and Merciful.

91. There is no blame on those who are weak or ill or who find no resources to spend [in holy fighting (Jihâd)], if they are sincere and true (in duty) to Allâh and His Messenger.[18] No ground (of complaint) can there be against the Muhsinûn (good-doers - See the footnote of V.9:120). And Allâh is Oft-Forgiving, Most Merciful.

[18] (V.9:91) CHAPTER. The Statement of the Prophet صلى الله عليه وسلم : "Religion is An-Nasîhah (to be sincere and true) to: 1. Allâh جل جلاله i.e. [obeying Him, by following His Religion of Islamic Monotheism, attributing to Him what He deserves and doing Jihâd for His sake and to believe in Him, to fear Him much (abstain from all kinds of sins and evil deeds which He has forbidden) and love Him much (perform all kinds of good deeds which He has ordained)], 2. to Allâh’s Messenger [i.e., to respect him greatly and to believe that he (صلى الله عليه وسلم) is Allâh’s Messenger, and to fight on his behalf both in his lifetime and after his death and to follow his Sunnah - (legal ways)] 3. to the Muslim rulers [i.e. to help them in their job of leading Muslims to the right path and alarm them if they are heedless] and 4. to all the Muslims (in common) [i.e. to order them for Al-Ma‘rûf (i.e. Islâmic Monotheism, and all that Islâm orders one to do), and to forbid them from Al-Munkar (i.e. disbelief, polytheism of all kinds, and all that Islâm has forbidden), and to be merciful and kind to them].
And the Statement of Allâh تعالى : "If they are sincere and true (in duty) to Allâh (جل جلاله) and His Messenger (Muhammad صلى الله عليه وسلم)." (V.9:91)
Narrated, Jarîr bin Abdullâh رضي الله عنه : I gave the Bai‘a (pledge) to Allâh’s Messenger صلى الله عليه وسلم for the following:
1. Iqâmat-as-Salât (to perform prayers).
2. To pay the Zakât .
3. And to be sincere and true to every Muslim [i.e. to order them for Al-Ma‘rûf (i.e. Islâmic Monotheism, and all that Islâm orders one to do), and to forbid them from Al-Munkar (i.e. disbelief, polytheism of all kinds, and all that Islâm has forbidden), and to help them, and to be merciful and kind to them]. (Sahih Al-Bukhâri, Vol.1, Hadîth No.54 and its Chapter No.43).

Not unto the weak nor unto the sick nor unto those who can find naught to spend is any fault (to be imputed though they stay at home) if they are true to Allah and His messenger. Not unto the good is there any road (of blame). Allah is Forgiving, Merciful.
