Assalamu Alaikum wa Rahmatullahi wa Barkatuh!
Kaab Ibn Ujrah (Radi Allah Anhu) relates
that Rasulullah (Sallallaho Alaihi Wassallam) said,
'Come near to the mimbar' and we came near the mimbar.
When He (Sallallaho Alaihi Wassallam) climbed the first step of the mimbar,
He (Sallallaho Alaihi Wassalla) said "Aameen",
When He (Sallallaho Alaihi Wassallam) ascended the second step,
He (Sallallaho Alaihi Wassallam) said "Aameen",
When He (Sallallaho Alaihi Wassallam) climbed the third step,
He (Sallallaho Alaihi Wassallam) said "Aameen"
When He (Sallallaho Alaihi Wassallam) came down,
We said
"O Rasool of Allah (Sallallaho Alaihi Wassallam),
we have heard from you today something which we never heard before"
He (Sallallaho Alaihi wasallam) said,
When I climbed the first step,
the angel Jibraeel (A.S.) appeared before me and said,
"Destruction to him who found
the blessed month of Ramdhan and let it pass by
without gaining forgiveness."
upon that I said 'Aameen'.
When I climbed the second step, he said,
"Destruction to him before whom your name is taken
and then he does not make Dua of Allah's blessing for you."
(by saying, for example Sallallaho Alaihi wasallam)."
I replied 'Aameen'.
When I climbed the third step, he said
"Destruction unto him in whose lifetime
his parents or either one of them reaches old age,
and (through failure to serve them)
he is not allowed to enter Jannah".
I said 'Aameen'.

Note
In this Hadith, it appears that
Jibraeel (Alaihi Salaam) gave expression to three curses,
upon which Rasulullah (Sallallaho Alaihi wasallam) said Aameen every time.
In al-Durr al-Mansoor it is reported that Jibraeel (Alaihi Salaam) advised
Rasulullah (Sallallaho Alaihi Wasallam) to say Aameen.
Being an Angel of such high mark, Jibraeel 's giving these curses is sure
to be accepted.
May Allah (Subhanahu wa Taala) in His infinite mercy
grant us His help and save us from these three dangers.
