al-Khaṭīb al-Baghdādī (رَحِمَهُ ٱللّٰهُ) said,

“It reached ash-Shāfiʿī that a person disparaged a man. So he asked, ‘For what reason did he disparage him?’ He said, ‘I saw him urinating while standing.’ It was said to him, ‘And what is (the issue) in that which entails his disparagement?’ He said, ‘Because the (urine) sprinkles fall on him and his clothes, then he prays (in that state).’ So it was said to him, ‘Did you see him pray like that?’ He said, ‘No’. So this and its likes is disparagement based on construed interpretation, and a scholar does not disparage anyone with that or the likes of it.”
