All festivals that go against the festivals that are prescribed in Islam are bid’ahs and innovations that were not known at the time of the righteous salaf, and they may have come from the non-Muslims, in which case as well as being innovations they also entail imitating the enemies of Allaah. The Islamic festivals are well known to the Muslims, namely Eid al-Fitr and Eid al-Adha, and the weekly festival (Jumu’ah or Friday).
There are no other festivals in Islam apart from these three. All festivals which have been introduced apart from these are to be rejected and are false according to the law of Allaah, because the Prophet (peace and blessings of Allaah be upon him) said: “Whoever innovates something in this matter of ours (Islam) that is not part of it will have it rejected,” i.e., it will be thrown back at him and will not be accepted by Allaah. According to another version, “Whoever does something that is not in accordance with this matter of ours (Islam) will have it rejected.” Once this is clear, it is not permissible to celebrate the holiday mentioned in the question, which is known as Mother’s Day, and it is not permissible to introduce any of the symbols of that holiday such as expressing joy and happiness, giving gifts and so on. The Muslim must be proud of his religion and adhere to the limits set by Allaah for His slaves, without adding anything or taking anything away. Moreover, the Muslim should not be weak and spineless, following anyone who makes noise, rather he should mould his character according to the sharee’ah of Allaah so that he will be followed, not following, and so that he will be an example, not one who follows the example of others, because the sharee’ah of Allaah – praise be to Allaah – is perfect in all ways, as Allaah says (interpretation of the meaning):
“This day, I have perfected your religion for you, completed My Favour upon you, and have chosen for you Islam as your religion” [al-Maa’idah 5:2]
Mothers deserve more than to be honoured on just one day of the year, rather mothers have rights over their children, who should look after them, take care of them and obey them, so long as that does not involve disobeying Allaah, at all times and in all places.
