Ramadan is the month of developing awareness and vigilance of the heart and actions; this is the month to learn about the status of your piety. This is the month of showing gratitude to Allah, the month to gain rushd (status to gain guidance mixed with wisdom, vision).
Ramadan is the time to behave with the qualities..
beloved to Allah such as generosity, humbleness and humility,
exercising forgiveness and pardon towards others,
taking care about people’s needs
and to be nice and compassionate to them,
to love goodness for others...
All in all, it is the time to show the best of you to Allah SWT. For the believers, this month is like the intensive care unit, the rehab center, the tune up month, their bank-Ilahi account, their business investment—both for dunya and akhirah.
