Abu Huraira reported

I invited my mother, who was a polytlieist, to Islam. I invited her one day and she said to me something about Allah's Messenger (ﷺ) which I hated. I came to Allah's Messenger (ﷺ) weeping and said: Allah's Messenger, I invited my mother to Islam but she did not accept (my invitation). I invited her today but she said to me something which I did not like. (Kindly) supplicate Allah that He may set the mother of Abu Huraira right. Thereupon Allah's Messenger (ﷺ) said: O Allah, set the mother of Abu Huraira on the right path. I came out quite pleased with the supplication of Allah's Messenger (ﷺ) and when I came near the door it was closed from within. My mother heard the noise of my footsteps and she said: Abu Huraira, just wait. And I heard the noise of falling of water. She took a bath and put on the shirt and quickly covered her head with a headdress and opened the door and then said: Abu Huraira, I bear witness to the fact that there is no god but Allah and Muhammad is His bondsman and His Messenger. He (Abu Huraira) said: I went back to Allah's Messenger (ﷺ) and (this time) I was shedding the tears of joy. I said: Allah's Messenger, be happy, for Allah has responded to your supplication and He has set on the right path the mother of Abu Huraira. He (the Holy Prophet ) praised Allah, and extolled Him and uttered good words. I said: Allah's Messenger, supplicate to Allah so that He may instill love of mine and that of my mother too in the believing servants and let our hearts be filled with their love, whereupon Allah's Messenger (ﷺ) said: O Allah, let there be love of these servants of yours, i.e. Abu Huraira and his mother, in the hearts of the believing servants and let their hearts be filled with the love of the believing servants. (Abu Huraira said: This prayer) was so well granted by Allah that no believer was ever born who heard of me and who saw me but did not love me.
