Is it a sin to neglect studying Islamic jurisprudence?

Question:
The pursuit of a livelihood has crowded out the pursuit of religious knowledge, so men and women have come to be ignorant of much of what concerns worship and transactions. There is no longer a place for studying Islamic jurisprudence in a Muslim's time. What is the limit of what is obligatory to learn from the religion? And does one sin by neglecting the study of Islamic jurisprudence?

Answer:
Allah (Glorified and Exalted is He) says: : [Surat al-Taghabun: 16]. The obligatory knowledge is acquiring what helps you to understand what Allah has made obligatory, and knowing what Allah has made obligatory upon you, and what He has forbidden for you. This is the obligatory knowledge: it is to learn from your religion what you cannot afford to be ignorant of.
And so it is for the woman; she must learn from her religion what she cannot afford to be ignorant of. This is the obligation. It is done by knowing tawhid (the oneness of Allah) and its opposite, and knowing the names of Allah and His attributes, and what befits Him (Glorified and Exalted is He), and knowing His right upon His servants in terms of obedience, and what He has forbidden them from in terms of sins. This is so that one proceeds toward Allah with insight, so that one worships one's Lord with knowledge and guidance.
As for expanding in this so that one knows the types of beneficial sciences, and gains insight into them, and knows the recommended practices and the disliked ones, this is an extra merit, and it is not obligatory. However, it is an extra merit. Some scholars call it a collective obligation (fard kifayah), so that the community is not devoid of a scholar of what Allah has legislated, and a scholar of what Allah has forbidden or disliked.
But the individual obligation is that one must know what one cannot afford to be ignorant of. That is, one must know what one was created for, and what Allah has made obligatory upon one in terms of obeying Him and obeying His Messenger (peace and blessings be upon him). One must also know what Allah has forbidden so that one may avoid it. If one knows all of this, then one has fulfilled the obligation, and one's learning after that is from the recommended practices, and from the additional knowledge in the recommended practices. Expanding in knowledge is a matter of going from good to good, and from merit to merit. And whoever Allah grants ample time and the ability to perfect his knowledge, that is better and more appropriate, so that he may benefit people and benefit himself.
