Sa’d ibn Matar al-Murshidee narrates :
‘He would not accept any ill speech being mentioned of anyone in front of him, and he would refuse to answer questions which would mention ill of people – [and the] names of those from amongst the scholars and the du’aat. He would [then] affirm [his stance] upon the questioner [saying]:
“Have I not told you to ask but not to mention names of people? I will therefore not be answering your question.”’
