السلام عليكم ورحمة الله وبركاته أحسن الله إليك Ustadh, in the third lesson of Manhaj as Salikin you mentioned that Shaykh Sulayman al-Ruhayli benefitted us that we can act upon the Usool if we don’t know the exact ruling. To what extent can we rely on that? جزاك الله خيرا

Ustadh AbdulAziz al-Haqqan

It comes with more knowledge and practice in sha'a Allah where u will understand where and when u can apply the usool correctly. So keep seeking knowledge
