Advice to Those Having Performed Hajj

What is your advice to the one who has performed the obligatory "first" Hajj?

My advice is that he should fear Allah and be aware of Him in performing all that which Allah has obligated upon him in terms of other acts of worship such as Salah, Zakah, fasting, honouring the parents, enjoining family ties and being good to the creation of Allah and to the animals under ones ownership and other than this from that which Allah has commanded with. That which encompasses all of this is the statement of Allah:

"Verily, Allah enjoins Al-'Adl (justice) and Al-Ihsan (being patient in performing one's duties to Allah), and giving (help) to kith and kin: and forbids Al-Fahsha. (all evil deeds), and Al-Munkar (all that is prohibited), and Al-Baghi (all kinds of oppression), He admonishes you, that you may take heed. And fulfill the Covenant of Allah (Bay'ah: pledge for Islam) when you have covenanted, and break not the oaths after you have confirmed them, and indeed you have appointed Allah your surety. Verily! Allah knows what you do" [Noble Quran 16:90-91]
