The dhikr that is prescribed when breaking the fast

What is the ruling on the du'aa' from hadeeth which they say are
da'eef (weak), such as:
1 – Saying when breakingthe fast: "Allaahumma laka sumtu wa 'ala
rizqikaaftartu (O Allaah, for You Ihave fasted and by Your provision I
have broken the fast)."
2 – Ashhadu an laa ilaaha ill-Allaah astaghfir Allaah as'aluka
al-jannah wa a'oodhu bika min al-naar (I bear witness that there is no
god but Allaah, I ask Allaah for forgiveness, I ask You for Paradise
and Iseek refuge with You from the Fire).
Is this prescribed, permissible, not permissible, makrooh, notvalid or haraam?.
Praise be to Allaah.
Firstly:
Saying du'aa' in the wordsmentioned when breaking the fast was
narrated in a da'eef (weak) hadeeth which was narrated by Abu Dawood
(2358) from Mu'aadh ibn Zuhrah, who heard that the Prophet (peace and
blessings of Allaah be upon him) used to say, when he broke his fast,
"Allaahumma laka sumtu was 'ala rizqika aftartu (O Allaah, for You
Ihave fasted and by Your provision I have broken the fast)."
There is no need for this, because we have the report narrated by Abu
Dawood (2357) from Ibn 'Umar (may Allaah be pleased with him) who
said: When the Messengerof Allaah (peace and blessings of Allaah be
upon him) broke his fast, he would say: "Dhahaba al-zamau'a, wa
abtallat al-'urooq wa thabata al-ajr insha Allah (Thirst has gone, the
veins are moist, and the reward is assured, if Allaah wills)." This
hadeeth was classed as hasan by al-Albaani in Saheeh Abi Dawood.
Secondly:
It is mustahabb for the fasting person to say du'aa' whilst he is
fasting and when breaking the fast, because of the reportnarrated by
Ahmad (8030) from Abu Hurayrah(may Allaah be pleased with him) who
said: We said: O Messenger of Allaah, when we see you our hearts are
softened and we are people of the Hereafter, but when we leave you we
are attracted by this world and by our womenfolk and children. He
said: "If you were always as you are when you are with me, the angels
would shake hands with you andthey would visit you in your houses. If
you did not commit sin, Allaah would bring another people who would
commit sin so that He could forgive them." He said: We said: O
Messenger of Allaah, tell us about Paradise, what isit built of? He
said: "Bricksof gold and bricks of silver; its mortar is musk, its
pebbles are pearls and rubies, its soil is saffron. Whoever enters it
will be happy and will never be miserable, he will abide therein
forever and never die. His clothes will never wear out and his youth
will never fade. There are three whose du'aa' will not be rejected: a
just ruler, a fasting person until he breaks the fast, and the prayer
of one who has been wronged. Itis borne on the clouds andthe gates of
heaven are opened for it, and the Lord, may He be glorified and
exalted, says: 'By My glory, I will grant you help even if it is after
some time.'"
This hadeeth was classed as saheeh by Shu'ayb al-Arna'oot in Tahqeeq al-Musnad.
It was also narrated by al-Tirmidhi (2525) with the words, "… the
fasting person when he breaks his fast…" This was classed as saheeh by
al-Albaani in Saheeh al-Tirmidhi.
So you may ask Allaah for Paradise and seek refuge with Him from the
Fire, and you can pray for forgiveness, and offer other du'aa's that
are prescribed in Islam. As for the du'aa' in this particular form –
Ashhaduan laa ilaaha ill-Allaah astaghfir Allaah as'aluka al-jannah wa
a'oodhu bika min al-naar (I bear witness that there is no god but
Allaah, I ask Allaah for forgiveness, I ask You for Paradise and Iseek
refuge with You from the Fire) – we could not find any source for it.
And Allaah knows best.
