Fighting the show in the heart of the righteous predecessors

Yusuf ibn Hussein ar-Razi said:
“The most difficult and valuable thing in this world is sincerity. How much effort have I made to rip out of my heart the desire to do something for show, but it seems that it is only mutating and growing with renewed vigor. “ 

Mutarrif ibn ‘Abdullah appealed to Allah with the following prayer:
“O Allah, I ask You for forgiveness for what I repented of before You, and then I did it again, and I ask You for forgiveness for what I promised You to do. , but did not, and I ask You for forgiveness for what I claimed that it was done by me for the sake of Your Face, but in fact what You know was mixed with it. ” 

Sufyan Sauri said:
“The hardest thing for me was to control my intention, because it was constantly changing and eluding me.” 

Yusuf ibn Asbat said: 
“For the one who does any deed, it is more difficult to cleanse the intention from all defilement than to exert a lot of effort.” 

Nafi ‘ibn Jubair once said:
“Do you wish to take part in the funeral prayer and funeral?” He replied: “Wait, I will,” – after which he thought for a while, and then said: “Forward!”
