As Salaamu Alaykum, below is the English translation of the Famous Haani an li Ibrahima of Shaykh Ibrahim Niass which is brought  to us by Amadou Bassirou Diop. 

In the Name of Allah, the Beneficent, the Merciful.

Hanî-an li-ibrâhima lâha hilâluhu Hilâlun badà li-nazirîna jamâluhu
Hilâlu rabî-in fihi jâ-a muhammadun Fatamma lanâl buchrà wa amma nawâluhu
li-afdali ardin halla afdalu mursalin bi-afdali yawmin, fastabâna kamâluhu
qad_ikhtîra min kullil awâlim asluhu kamâ _khtîra, wa_khtîrat lizâka fi-âluhu
muhammadun mukh-târun wa âdamu tînatun muhammadun, yawmal ba-a°thi, râqa khisâluhu

alayhi salâtu llahi çumma salâmuhu bihâ khussisal as-hâbu turrab w âluhu.

Congratulations to Ibrahim (AS) with the appearance of Your Moon (Muhammad ibn Abdallah pbuh), That which appears to the Observers in all its Beauty

The moon of the Rabî-a month, month of the birth of Muhammad (pbuh), Month of the good news and propagation of his benefits

The Best Prophet settled in the best region, in the best day, and his Completeness was achieved

He was selected Best Ascent among Creatures, As He was selected, in the same way Best Endeavor

Muhammad (pbuh) was elected whereas Adam was only mud and, with resurrection, his qualities will be dazzling (1)

Muhammad is the Light of Creation and He is the Elected, Him the Great, the Noble of character, with Complete Majesty.

On him the Peace of God and his Reverence, by which, He drives away the punishments (2): and it is indeed time that You drive them away

 On him the Peace of God and His Salutation, by which, You grant access to Your Servant (2) Barham (RA) to the Sealed Enclosure

On him the Peace of God and his Safety, by which, He massacres the enemy of the religion: it is You whom they fight.

On him the Peace of God and His Honors, by which, the misfortune of my (3) enemy, by you, is somehow hardened.

On him the Peace of God and His Regards, by which, each time the moon appears in the Sky

 On him the Peace of God and his Blessings, Reserved to His companions and His Family.

Notes:

(1) Resurrection, He (the Prophet Muhammad) will be the resurrected, the first to enter to the paradise but especially, he will be the intercessor. When all creatures seek the intercession near the prophets, they will decline the mission. Then, Muhammad will say: Yes, it is for me. He will be the guide of all, the Imam of the Imams.

(2) Signs of modesty on behalf of the author, whose name is Barham (Shaykh Al Islam Shaykh Ibrahim Niass)

 (3) Yes, because his enemy is that of God. The one who fights him by error, on the basis of false information. Elsewhere, he requests God to show him  his true nature
