Noorani Qaida page 28 guides you to learn double Tashdeed in words. Tricky but you enjoy learning them. The previous lesson is about Tashdeed and Sukoon. However, this lesson is related to Tashdeed with Tashdeed. Firstly, you see that a letter has Tashdeed and after the Tashdeed letter there is Sukoon above the next letter. Similarly, in this lesson, you will see that both letters have Tashdeed above the letter. For instance, ” يُحِبُّ” (yuhibbu) you can see that letters have Tashdeed only there is no Sukoon above the letters.
