"Barakah in time" simply means blessings from Allah that enable us to accomplish more than usual in a short time. For example, many Muslims scholars of the past published multiple books in a very short time. The reason for this amazing productivity is “barakah.”
Ramadan is the perfect time for the family to bond and grow in Imaan together. The devils are locked up and everybody is more spiritual. This spirituality needs to be nurtured so that we can benefit from it after Ramadan.
