Imam Ahmed Alhasan احمد الحسن a.s said
Hold tight to the One Who has created everything and has given everything its creation.
And accept everything that He SWT. informs you of and you shall know everything
and you will not get lost and you will not be misguided even if all the people of the earth got lost and misguided.
With The Righteous Servant – Part 1
قال الامام احمد الحسن ع
تمسك بالذي فطر كل شيء وأعطى كل شيء خلقه
واقبل كل ما يخبرك به سبحانه تعرف كل شيء منه
ولن تضيع ، ولن تضل
ولو ضاع وضلّ أهل الأرض بأجمعهم
مع العبد الصالح
