Praise be to Allah.We Sunnis wish all people well, and we ask Allaah to guide all those who are misled and to reward all those who obey Him. We hope that Allaah will guide those Raafidis…
The differences between the Ahl al-Sunnah (Sunnis) and the Raafidis are very great and are fundamental. For example, the Raafidis say that the Qur’aan was altered, and they condemn most of the Sahaabah (may Allaah be pleased with them) and think that they went astray; they exaggerate about their imaams and worship them, and give them precedence over the Prophets and angels; they go on pilgrimages to mashhads (shrines) and graves, where they do all kinds of actions of shirk, associating others in worship with Allaah.

We advise you to read "Al-Khutoot al-‘Areedah" by Muhibb al-Deen al-Khateeb [this book is available in English – Translator], or Mukhtasar al-Tuhfat al-Ithna’ ‘Ashariyyah by al-Dahlawi, or Fikrat al-Taqreeb bayna Ahl al-Sunnah wa’l-Shee’ah by Naasir al-Qaffaari.
And we advise you not to think of marrying this man… Whoever gives up something for the sake of Allaah, Allaah will compensate him with something better. We ask Allaah to make you strong and grant you a good life in this world and in the Hereafter.
We would also remind you that it is not permitted to have relationships with non-mahram men, as you will find explained clearly in Questions 2005 , 9465 And 1114 We ask Allaah to help you to do all that is good.
