The real object is not the specific rites of pilgrimage but true devotion to Allah and submission to His will which are inherent in those rites
لَن يَنَالَ اللَّـهَ لُحُومُهَا (It is neither their flesh nor their blood that reaches Allah - 22:37) It means that the sacrifice of animals is a very high form of worship, but their meat and blood do not reach Allah Ta’ ala nor are these two things the real object of sacrifice. Its real aim is to recite the name of Allah and to comply with His commands with true devotion. This rule applies to all forms of worship. For instance, the object of prayers is not just the movement of limbs, or the object of fasting is not merely a denial of food and drink. The real purpose of these rites of worship is to obey the commands of Allah Ta’ ala with all sincerity. Devoid of sincerity these rites of worship are like a body without soul. Nevertheless these forms of worship are also very important because Allah Ta’ ala has prescribed these forms for different types of worship. Allah knows best. واللہ اعلم
