I collected the following for a leaflet. But thought I'd post them here anyway.
It was narrated that Abu Hurayrah (may Allaah be pleased with him) said: A man came to the Messenger of Allaah (peace and blessings of Allaah be upon him) and said, “O Messenger of Allaah, who among people is most deserving of my good company?” He said, “Your mother.” He asked, “Then who?” He said, “Your mother.” He asked, “Then who?” He said, “Your mother.” He asked, “Then who?” He said, “Then your father.” (Narrated by al-Bukhaari, 5626; Muslim, 2548)
Allah Ta’ala says in the Holy Qur’an, “Say (O beloved Prophet): Come, I will recite to you what your Lord has forbidden you: that you associate nothing with Him and that you do good to parents…” (6:151). Allah Ta’ala also says, “And we have enjoined upon man concerning his parents: his mother bore him in weakness upon weakness, and his weaning is in two years. Therefore, show gratitude to Me and to both your parents: unto Me is the eventual journeying.” (31:14)
Quran.
"Your Lord has commanded that you worship none but Him, and that you be kind to your parents. If either or both of them reach old age with you, do not say to them any word of contempt, nor repulse them, but address them in terms of honor, and out of kindness lower to them your wings of submission, and say, 'My Lord, have mercy on them as they cared for me in my childhood"' (17:23-24).
the Holy Quran recalls the covenant the Sons of Israel held with Allah (SWT): "And (remember) when We took a covenant from the Children of Israel, (saying): Worship none but Allah and be good to parents…"(2:83). (5) As presented in the above verse, this message was not only revealed to Prophet Muhammad (PBUH&HP), rather it was identically revealed to all prophets.
Allah (SWT) has disallowed us from saying even the smallest thing that might upset our parents. Imam Sadiq (PBUH) interprets this verse (17:23) and says: "If there was any word tinier than 'Fie' to upset one's parents, Allah would have banned people from using that." (10)
''They ask you as to what they should spend in charity. Say: Whatever wealth you spend, it should be for the parents and the near of kin and the orphans and the needy and the wayfarer, and whatever good you do, Allah surely knows it.'' (The Holy Quran, 2:215)
''Say: Come I will recite what your Lord has forbidden to you-- that you do not associate anything with Him and show kindness to your parents, and do not slay your children for (fear of) poverty; We provide sustenance for you and for them. Do not approach the shameful deeds, whether open or secret; and do take life, which Allah has made sacred except for the requirements of justice; This He has command you, with that you may understand.'' (The Holy Quran, 6:151)
''And if they tried that you should associate with Me what you have no knowledge of (but you know this is wrong), do not obey them; and keep company with them in this world kindly… '' (The Holy Quran, 31:15)
7- ''And We have enjoined on man doing of good to his parents; with trouble did his mother bear him, and with trouble did she bring him forth; and the bearing of him and the breastfeeding of him was thirty months…'' (The Holy Quran, 46:15)
8- ''And We have enjoined man in respect of his parents: his mother bears him with travail upon travail, and his breastfeeding takes two years. (We enjoined him) Be grateful to Me and to both your parents; to Me is the eventual return.'' (The Holy Quran, 31:14)
9- ''Your Lord has commanded that you worship none but Him, and that be kind to your parents. Whether one or both of them attain old age in your life, say not to them a word of contempt (Fie), nor shout at them, but address them in terms of fine, correct and honorable words.'' (The Holy Quran, 17:23)
11- ''And, out of kindness, lower to them the wing of humility…'' (The Holy Quran, 17:24)
Abu Hurairah reported that a man came to the Messenger of Allah (peace be upon him) and asked: "O Messenger of Allah, who is the person who has the greatest right on me with regards to kindness and attention?" He replied, "Your mother." "Then who?" He replied, "Your mother." "Then who?" He replied, "Your mother." "Then who?" He replied, "Your father."
In another tradition, the Prophet advised a believer not to join the war against the Quraish in defense of Islam, but to look after his mother, saying that his service to his mother would be a cause of his salvation. Mu'awiyah, the son of Jahimah, reported that Jahimah came to the Prophet (peace be upon him) and said, " Messenger of Allah! I want to join the fighting (in the path of Allah) and I have come to seek your advice." He said, "Then remain in your mother's service, because Paradise is under her feet."
"O you who believe! Save yourselves and your families from a fire whose fuel is men and stones, over which are set angels strong and severe, who do not disobey Allah in what He commands them, but do as they are commanded." Holy Qur'an (68:6)
Our Lord! Forgive me and my parents and believers on the day when the account is cast. [14:41]
(Don't wait until Mother's Day. In Islam a mother should be shown how important and loved she is every single day, not once in a year.
