Re: Maulana Maudodi
He wasn’t shia-leaning per se. I believe the issue was that he wrote a line that was critical of Hazrat Uthman’s (ra) record as a ruler.
Many sunni scholars who were his peers were horrified by this and argued that any criticism of him was an insult to him. Maududi refused to retract his comments, arguing that he did not intend to and did not insult Hazrat Uthman, but was writing on what actually happened.
