Shaykh 'Abdul Qadir Gilani.

A contemporary of Shaykh 'Abdul Qadir reports: "His prayers were readily answered. Being extremely tender-hearted, he would burst into tears (if anything sorrowful or touching was mentioned to him). More often he was to be found immersed in meditation and recollection of Allah. He was softhearted, courteous, cheerful, generous and compassionate. Being the offspring of a noble family, he was also highly reputed for his profound knowledge and piety." (Abu 'Abdullah Muhammad ibn Yusuf al Barzali in Tabaqat al Kubra)

The testimony of another scholar of those times runs as follows: "Always disposed to avoid things unseemly and indecorous, he only pressed for the desirable and befitting. He would boil with indignation if the Divine commandments were overstepped but remained listless to the wrongs and ill-treatments to his own person. He would never seek revenge save for the sake of Allah nor send back a beggar without giving him something. If he had nothing to give, he would part with the clothes he had been putting on."(Muhyiuddin Abu 'Abdullah Muhammad ibn Haamid al Baghdadi in Qalaa'id al Jawaahir)
