Ibn 'Abd al-Barr quoted in his Jami' bayan al-'Ilm wa fadlih جامع بيان العلم وفضله a statement of imam Sufyan a-Thawri سفيان بن سعيد الثوري with a -apparently- conected narrator chain saying -as if it was a hadith-:
In the following I will translate from Arabic as this is my own translation take it carefully -corrections/inputs are welcome-
" إِنَّمَا الْعِلْمُ عِنْدَنَا الرُّخْصَةُ مِنْ ثِقَةٍ ، فَأَمَّا التَّشْدِيدُ فَيُحْسِنُهُ كُلُّ أَحَدٍ ".
(Real) Knowledge with us (in our opinion) is a permission from a trustworthy person, while rigour can be made (declared) by anybody
This statement is about fatwa as it was quoted in a chapter about fiqh and its knowledge base.
This statement is also often used and quoted in books of sheikh Yusuf al-Qaradawi who consider seeking easier "verdicts" as essential.
What are the limits of such permissions or easier verdicts?
And how is this statement interpreted and when does it apply?
