Shaykh Bin Baaz, may Allah have mercy upon him, was asked if there is anything specific to welcome the month of Ramadan with,

An excerpt of his answer:

…ولا أعلم شيئاً معيناً لاستقبال رمضان سوى أن يستقبله المسلم بالفرح والسرور والاغتباط وشكر الله أن بلغه رمضان،

“I am unaware of something specific to welcome the month of Ramadan with, other than a Muslim welcoming it with joy and happiness and with pleasure and by thanking Allah that he made him reach the month of Ramadan”

ووفقه فجعله من الأحياء الذين يتنافسون في صالح العمل، فإن بلوغ رمضان نعمة عظيمة من الله.

“And that he granted him success, whereas he made him from the living who are competing with one another in righteous good deeds , for verily reaching the month of Ramadan is a great blessing.”

ولهذا كان النبي صلى الله عليه وسلم يبشر أصحابه بقدوم رمضان مبيناً فضائله وما أعد الله فيه للصائمين والقائمين من الثواب العظيم،

“Thus the Prophet , alayhi salaatu was-salaam, use to give glad tidings of the coming of Ramadan, clarifying its virtues and what Allah prepared therein for those fasting and standing in night prayers of a great reward.”

ويشرع للمسلم استقبال هذا الشهر الكريم بالتوبة النصوح والاستعداد لصيامه وقيامه بنية صالحة وعزيمة صادقة.

“Likewise what is legislated for the Muslim to welcome this noble month with sincere repentance, and with preparation for its fasting and its standings in night prayers by having an upright intention and a truthful determination.”
