AL-DIMASHQI'S SOUL-ENRICHING NAATH ON THE MEELAD 
Hafiz Shams al-Din Ibn Nasir al-Din al-Dimashqi (radi Allahu anhu) has written in his book "Mawrid al-Sadi fi Mawlid al-Hadi": "It is established in Sahih Ahadith that punishment is lessened for Abu Lahab every Monday because he said Thuwaibah free out of joy and happiness at the birth of the Noble Prophet (sallal laahu alaihi wasallam). After this he wrote the following lines of poetry: 
When this is a Kafir and his censure has come (in theQuran) 
Perish his hands in the fire of Hell forever  
It has been narrated that always on a Monday 
(His punishment) is lessened because of his happiness at (the birth of) Ahmad 
What is the view then about the servant (of Allah) whospent his whole life  
Being happy at (the birth of ) Ahmad and died an upholderof Tawhid?"

PRACTICE OF A SHEIKH OF A TARIQAH 
Kamal Adfiri states in "al-Tali al-Sa'id" that his reliable and trustworthy friend Nasir al-Din Mahmud Ibn al-'Imad related that Abu al-Tayyib Muhammad Ibn Ibrahim al-Sibti al-Maliki, a resident of Tus and one of the pious Ulama, used to pass by the Madrassah on the birthday of the Noble Prophet (sallal laahu alaihi wasallam) and say, "O Jurist! Today is the day of Eid. Give the students a holiday and send them home". Thus they used to give them a holiday and send them home.

This is evidence of his confirmation and absence of rejection. This gentlemen was a famous Jurist of the Maliki School of Law, who had a command over many branches of knowledge and was a God-conscious and pious elder. Abu Hayyan and others have transmitted narrations from him. He passed away in the year 695 A.H.

CONCLUSION 
Ibn al-Haj has written that if it is questioned as to wisdom in the birth of the Noble Prophet (sallal laahu alaihi wasallam) being in the month of Rabi-ul-Awwal and on Monday not in the month of Ramadaan al-Sharif, which is the month of the sending down of the Quran and in which Lailatul-Qadr is found, nor in any of the sacred months nor on the fifteenth of Shabaan al-Mu'azzam, nor on Friday, nor on the night of Friday – then the reply can be given from four angles: 
(1) It has been transmitted in Hadith literature that Allah Ta'ala created the trees on a Monday. In this there is great admonition and that is that on a Monday Allah Ta'ala created food, sustenance, fruits and the things given in charity. Mankind's growth development and livelihood are closely connected with these and men's selves get joy from them.

(2) In the word Rabi' from the point of view of its etymology, a good indication and a virtuous omen is found. Abu al-Rahman al-Saqli states that for every man his name is a part for him (i.e. his name has effects on his body).

(3) The reason of Rabi' (i.e. spring) is the most moderate and beautiful of all the seasons. And the Shari'ah of the Noble Prophet (sallal laahu alaihi wasallam) is the most moderate and the easiest among all the Shara'i. 

(4) Allah, the All-Knowing and All-Wise, wanted to bestow eminence on that time in which the Noble Prophet (sallal laahu alaihi wasallam) entered this world. Had he been born in any of the above-mentioned sanctified times, then the illusion may have arisen that the nobility and eminence of the Noble Prophet (sallal laahu alaihi wasallam) are on account of those sanctified times.
