Here is Book 4 of the 'Let's Learn Hadith' colouring book series. Alhamdulillah, I was able to find Books 5 and 6 but unfortunately, still no books 2 & 3. Next week insha'allah, I'll upload books 5 and 6, so check back for those insha'Allah.
Maybe, I'll design some games to be used with these colouring books insha'Allah. We'll see insha'Allah. Enjoy insha'Allah!
