May Allah preserve you. If I get intrusive thoughts or claims about Allah, the Prophet ﷺ, and I reject them and hate them, but sometimes analyze and check in my mind whether they could be true to reassure myself they're not because they keep coming, is this ridda, kufr, and should i renew my nikah?

Ustadh AbdulAziz al-Haqqan
You should see a muslim trustworthy psychiatrist asap may Allah protect us and you ameen.
