What are the relaxations Allah has given for Sick people for striving in the way of Allah?

لَّيۡسَ عَلَى ٱلضُّعَفَآءِ وَلَا عَلَى ٱلۡمَرۡضَىٰ وَلَا عَلَى ٱلَّذِينَ لَا يَجِدُونَ مَا يُنفِقُونَ حَرَجٌ إِذَا نَصَحُواْ لِلَّهِ وَرَسُولِهِۦۚ مَا عَلَى ٱلۡمُحۡسِنِينَ مِن سَبِيلٖۚ وَٱللَّهُ غَفُورٞ رَّحِيمٞ ٩١

[9:91] There is no blame on the weak nor on the sick nor on those who have nothing to enable them to join (the struggle in the Way of Allah) if they stay behind provided that they are sincere to Allah and to His Messenger. There is no cause for reproach against those who do good. Allah is All-Forgiving, Ever Merciful.

Zaeef (old) aur beemar log aur woh log jo shirkat e jihad ke liye raah nahin paatey, agar peechey reh jayein to koi harj nahin jabke woh khuloos e dil ke saath Allah aur uske Rasool ke wafadaar hon. Aisey mohsineen par aitraz ki koi gunjaish nahin hai aur Allah darguzar karne wala aur reham farmane wala hai

لَّيۡسَ عَلَى ٱلۡأَعۡمَىٰ حَرَجٞ وَلَا عَلَى ٱلۡأَعۡرَجِ حَرَجٞ وَلَا عَلَى ٱلۡمَرِيضِ حَرَجٞۗ وَمَن يُطِعِ ٱللَّهَ وَرَسُولَهُۥ يُدۡخِلۡهُ جَنَّٰتٖ تَجۡرِي مِن تَحۡتِهَا ٱلۡأَنۡهَٰرُۖ وَمَن يَتَوَلَّ يُعَذِّبۡهُ عَذَابًا أَلِيمٗا ١٧

There is no blame on the blind, nor on the lame, nor on the sick (if they do not go forth to fight). Allah will admit those who obey Allah and His Messenger to the Gardens beneath which rivers flow and will inflict a grievous chastisement on those who turn away.

Agar andha aur langda aur mareez jihad ke liye na aaye to koi haraj nahin. Jo koi Allah aur uske Rasool ki itaat karega Allah usey un jannaton mein dakhil karega jinke nichey nehrein beh rahi hongi, aur jo mooh pherega usey woh dardnaak azaab dega”
