there is no blame on the weak nor on the sick nor on those who have nothing to enable them to join 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 allforgiving ever merciful.
ليس على الضعفاء ولا على المرضى ولا على الذين لا يجدون ما ينفقون حرج إذا نصحوا لله ورسوله ما على المحسنين من سبيل والله غفور رحيم
