Surah At-Taubah, Ayat 113-114

Ayat 113. It is not (proper) for the Prophet  [SAWW](PBUH) and those who believe to ask Allah's Forgiveness for the Mushrikun (polytheists, idolaters, pagans, disbelievers in the Oneness of Allah) even though they be of kin, after it has become clear to them that they are the dwellers of the Fire (because they died in a state of disbelief).  

Ayat 114. And [Ibrahim's (Abraham)] invoking (of Allah) for his father's forgiveness was only because of a promise he [Ibrahim (Abraham)] had made to him (his father). But when it became clear to him [Ibrahim (Abraham)] that he (his father) is an enemy to Allah, he dissociated himself from him. Verily Ibrahim (Abraham) was Al-Awwah (has fifteen different meanings but the correct one seems to be that he used to invoke Allah with humility, glorify Him and remember Him much), and was forbearing.

Hazrat Abdullah bin Amr bin Al'as (May Allah be pleased with him) reported: The Prophet  [SAWW](PBUH) recited the Words of Allah, the Exalted, and the Glorious, about Ibrahim (PBUH) who said: "O my Rubb! They have led astray many among mankind. But whosoever follows me, he verily, is of me". (14:36) and those of `Isa (Jesus) (PBUH) who said: "If You punish them, they are Your slaves, and if You forgive them, verily, You, only You, are the All-Mighty, the All-Wise". (5:118). Then he  [SAWW](PBUH) raised up his hands and said, "O Allah! My Ummah, my Ummah,'' and wept; Allah, the Exalted, said: "O Jibril (Gabriel)! Go to Muhammad  [SAWW](PBUH) and ask him: `What makes you weep?" So Jibril came to him and asked him (the reason of his weeping) and the Messenger of Allah informed him what he had said (though Allah knew it well). Upon this Allah said: "Jibril, go to Muhammad  [SAWW](PBUH) and say: `Verily, We will please you with regard to your Ummah and will never displease you". [Muslim Hadith # 0397].

Lesson : as mentioned above in Surah At-Taubah Ayat 114. "But when it became clear to him [Ibrahim (Abraham)] that he (his father) is an enemy to Allah, he dissociated himself from him". This Hadith makes two points clear: Firstly, the kindness and mercy which the Prophet  [SAWW](PBUH) had for his Ummah, a full manifestation of which will be seen on the Day of Resurrection. Secondly, the love that Allah has for His Prophet, Muhammad  [SAWW](PBUH). Both these benefits will then go to the advantage of the faithful Muslims as they will be then blessed with Mercy and forgiveness of Allah. May Allah include us among them.
