Shaykh Shah Wasiullah Allahabadi (Allah have mercy on him) said that,

‘The author of Ruh al-Ma’ani has explained the meaning of ‘good of this world’ as sound health and serenity (‘afiyet).’

What is ‘afiyet?

Our master Shaykh Ahmad Kabir Rifai (Allah have mercy on him) said,

‘Be considerate of the blessing of serenity. The reality of which is that the process of breathing continues without discomfort, the daily sustains is achieved without (much) hardship and the good actions are done without ostentation.”
