I do not celebrate specific days for mothers or fathers, i beleive every day should be a respectable and honourable day for our parents. But since some do, i thought it necessary to share a well known hadith on the importance of mothers.
Prophet Muhammad (Peace be Upon Him) statements
Abu Hurairah (May Allah be pleased with him)reported: A person came to Messenger of Allah (PBUH) and asked, "Who among people is most deserving of my fine treatment?'' He (PBUH) said, "Your mother". He again asked, ``Who next?'' "Your mother", the Prophet (PBUH) replied again. He asked, "Who next?'' He (the Prophet (PBUH))said again, "Your mother.'' He again asked, "Then who?'' Thereupon he (PBUH) said,'' Then your father.''
