I have the english version of aab-e-Kauthar , May be it would have been translator's mistake. I agree with both of your brother's. JazakAllah for rectifying my mistake. May Allah Azwajaal reward both of you. Please do dua for this Nacheez.
Salamun Alaykum It is not that i am saying the information you have given is wrong, but rather dispelling any possible bad opinion concerning Allah, and Allah knows best.
Salamun Alaykum Allah would never punish a progeny of a person for his sin, unless they follow him in that sin.
Bismillahir Rahmanir Raheem Assalamu 'Alaykum wa Rahmatullahi wa Barakatuhu JAZZALLAHU ANA SAYYEDINA MUHAMMADAN MA HUWA AHLAHU MANAM SAGHE DARBARE JILANI Khwaja-e-Khwajegaan Sayyedina Khwaja Bayazid Bustami Radi Allahu anhu was lying with his feet stretched. A mureed was sitting nearby. A man came and put his foot on that of Great Khwaja Radi Allahu anhu and went his way. The Mureed objected and said that it was Sayyedina Khwaja Bayazid Bustami Radi Allahu anhu. The Man replied So What? It so happened that when he was about to die both his feet turned black and this was not enough. To this day when anyone of his progeny is about to die his feet turn black. (Raunaq-ul-Majlis : pg:17) May Allah azwajaal with the waseela of Sayyedina RasoolAllah Salla Allahu ta'ala 'alayhi wa Sallam save us from such death and punishment. Yaa Rahim Huwal Rahim Haq Rahim JAZZALLAHU ANA SAYYEDINA MUHAMMADAN MA HUWA AHLAHU
