عن كعب بن عجرة رضي الله عنه قال قال رسول الله صلى الله عليه وسلم احضروا المنبر فحضرنا فلما ارتقى درجة قال آمين فلما ارتقى الدرجة الثانية قال آمين فلما ارتقى الدرجة الثالثة قال آمين فلما نزل قلنا يا رسول الله لقد سمعنا منك اليوم شيئا ما كنا نسمعه قال إن جبريل عليه السلام عرض لي فقال بعد من أدرك رمضان فلم يغفر له قلت آمين فلما رقيت الثانية قال بعد من ذكرت عنده فلم يصل عليك فقلت آمين فلما رقيت الثالثة قال بعد من أدرك أبويه الكبر عنده أو أحدهما فلم يدخلاه الجنة قلت آمين (الترغيب والترغيب #1479)

Hazrat Ka’b bin ‘Ujrah (radhiyallahu ‘anhu) reports the following: On one occasion, Rasulullah (sallallahu ‘alaihi wasallam) addressed the Sahaabah (radhiyallahu ‘anhum) saying, “Come close to the mimbar.” When we came close, Rasulullah (sallallahu ‘alaihi wasallam) ascended the mimbar. When he ascended the first step, he said “Aameen”. When he ascended the second step, he said “Aameen”. When he ascended the third step, he said “Aameen”. (When he descended from the mimbar after delivering the khutbah,) The Sahaabah (radhiyallahu ‘anhum) enquired, “O Rasulullah (sallallahu ‘alaihi wasallam)! We heard you mention something today that we did not hear from you previously (i.e. Rasulullah (sallallahu ‘alaihi wasallam) saying ‘Aameen’ thrice while ascending the mimbar).” Rasulullah (sallallahu ‘alaihi wasallam) said, “When I ascended the first step of the mimbar, Hazrat Jibra’eel (‘alaihis salaam) appeared before me and said, “Woe to him who witnessed the blessed month of Ramadhaan and let it pass without gaining forgiveness (i.e. he did not fulfill the rights of this month).” Upon that, I said ‘Aameen’. (When I ascended the second step of the mimbar,) he said, “Woe to him in whose presence your name is mentioned and he does not send salutations upon you.” I replied, ‘Aameen’. (When I ascended the third step of the mimbar,) he said, “Woe to that person in whose presence both or one of his parents attain old age and (through failing to serve them and fulfill their rights,) they do not become the means of him entering Jannah.” I said ‘Aameen’ (i.e. due to not serving them, he is deprived of entry into Jannah).”

يَا رَبِّ صَلِّ وَسَلِّمْ دَائِمًا اَبَدًا عَلَى حَبِيْبِكَ خَيْرِ الْخَلْقِ كُلِّهِمِ
