Blessings are Primary and Secondary
 
Blessings are divided into two different kinds: primary and secondary.
Having an abundance of wealth and knowledge, a strong body, observance of the nawafil [supererogatory acts of worship]such as waking up to pray at night, and reading the Qur’an frequently, and following the Sunnah of the Prophet in bodily cleanliness, perfuming oneself—in the case of men— when attending a gathering and shaking hands with those you meet, entering the mosque with one’s right foot and leaving it with the left, and removing harmful objects from paths and roads, as well as the many other actions performed by the Prophet which are recommended for us to emulate— all of these are examples of secondary blessings, but they are great in the eyes of those who know their true values.
Primary blessings are also numerous and infinite in number, the first of which is the belief in Allah the most Exalted and the Messengers and Books sent by Him, and implementing His commands and abiding by them. Other blessings include having a healthy body, eyes, ears and all other senses, which are the fulcrum for man’s essence and the foundation from which he may go forth and benefit from his existence. The blessing of knowledge is also a primary blessing that is essential for the advancement of humanity and its happiness in this life and the next, for knowledge is a lofty blessing which ever form it takes; seeking it is a blessing, benefiting from it and benefiting others by it is a blessing; preserving it and transmitting it to the following generations is a blessing, as is spreading it to people. There are many other examples of primary blessings, which I will not mention here out of respect for the value of time. One of the primary blessings, or the loftiest and most precious of all primary blessings is that of time, for the discussion of which these pages have been assembled, particularly its value for students and people of knowledge. Time is the substance of life, the sphere in which man exists, the citadel of his spirit, and his subsistence— him benefiting himself and others.
The Holy Qur’an indicated the greatness of this most primary of all blessings, and stated its supremacy over all the other blessings in many verses, of which I will mention but a few. Allah, most Exalted is He, said of His greatest blessing bestowed upon mankind:
Allah is He who created the heavens and the earth and causes water to descend from the sky, thereby producing fruits as food for you, and makes the ships to be of service unto you that they may run upon the sea at His command, and has made of service unto you the rivers; and makes the sun and the moon constant in their courses, to be of service unto you, and has made of service unto you the night and the day; And He gives you of all you ask of Him; and i f you count the favours of Allah, you will never number them. Man is indeed most unjust, most ungrateful.(14/32-34)
 Thus, Allah has granted His creation the blessings of day and night, which are the blessing of time that we elucidate, and in which we elucidate, and through which this world passes from its beginning to its end. Allah, most Exalted is He, says illuminating this highest of blessings in a second verse:
And He has constrained the night and the day and the sun and the moon to be of service to you, and the stars are made subservient By His command. Surely in this there are signs for people who reflect,  Thus Allah indicated at the end of the verse that in these blessings are indeed powerful signs for those who reflect and deliberate. (16/12)
And He, the most Glorified, said:
And We appoint the night and the day as two signs. Then We maked ark the sign of the night, and We make the sign of the day sight-giving, that you may seek bounty from your Lord, and that you may know the computation of the years, and the reckoning; and everything have We expounded with a clear expounding.(17/12)
And Allah the most Glorified said:
And of His signs are the night and the day and the sun and the moon. Prostrate yourselves neither to the moon nor to the sun; but prostrate to Allah Who created them, if it is in truth Him Whom you worship, Allah extolled Himself as the Lord of time and space and whatever exists in them: “ Unto Him belongs whatsoever rests in the night and the day. He is the Hearer, the Knower.” (41/37)
