Grateful on offering!
Whenever you utilize the offering of Allah (Subhanahu Wa Ta'ala), never forget the one who gave you. When you consider it to be the gift from Allah (Subhanahu Wa Ta'ala) there won't be any negligence. The only method is that one should ponder over the gifts bestowed upon him/her, which in turn will generate love and affection of Allah (Subhanahu Wa Ta'ala) and one will start appreciating and respecting it. One will not only begin pronouncing Alhumdulillah by tongue but also will express his/her thanks through the other body organs and will never spend those offerings in the disobedience of Allah (Subhanahu Wa Ta'ala). Hence respect the valuable gifts of Allah (Subhanahu Wa Ta'ala) bestowed upon you and be thankful to Him and do not become ungrateful.
However, when the offerings are bestowed upon the human beings instead of being thankful to Allah (Subhanahu Wa Ta'ala) they disregard them and becomes disobedient. Upon it some looseness is given to them, they are made to comprehend by various methods. The disobedient slave over it thinks that, if this act of mine was wrong then why wasn't I punished? He/she becomes courageous and then there's no limit of their disobedience. Now when the person reach at this point, then the door of evil and misfortune is opened upon oneself, and even now if he/she doesn't retrieve then they are completely ruined. Moreover one is also deprived from the forgiveness and thawab (reward) of the Judgement day.
When a slave of Allah (Subhanahu Wa Ta'ala) at the sight of the offerings, utters Alhumdulillah, then all the eight doors of Paradise are wide opened for him/her and they are allowed to enter it, through which ever door they prefer. On utterance of Alhumdulillah once he/she gets the 30 auspicious rewards. The blessing of it fills the vacant space present between the Earth and the skies. On the second time utterance of Alhumdulillah by a slave, then its radiance gets filled from the seventh layer of sky till the seventh layer of the Earth. When the slave pronounces Alhumdulillah for the third time, Allah (Subhanahu Wa Ta'ala) Himself gets attentive towards him/her. Only utterance of Alhumdulillah by tongue is not sufficient enough of being thankful on some gift but simultaneously spending it in the service of the slaves of Allah (Subhanahu Wa Ta'ala) is actually being thankful to it.
Indeed human being is very ungrateful. His/her greediness never allows them to respect the offerings. Which isn't there in his/her fate; he/she assumes it to be the gift and goes on striving for it. Such attempts made result in complete destruction. There shouldn't be any decrement in remembrance of Allah (Subhanahu Wa Ta'ala) before and after receiving an offering. The Heart should be in the same state which it was earlier and certainly it can happen and this is what which is asked for. If a person indulges himself/herself completely in the gifts bestowed upon them and forgets the remembrance of Allah (Subhanahu Wa Ta'ala) then the subject gift is snatched away. Envy and ungratefulness destroys away the auspicious rewards and gifts of oneself.
(Do not show negligence towards being thankful to Allah (Subhanahu Wa Ta'ala) on the bestowed gifts of Him.) Allah (Subhanahu Wa Ta'ala) never snatches away the gifts from His slaves on the basis of atheism but surely on being ingratitude on the bestowed favours.
Ungratefulness of favours even converts the Halal (permissible) food into a Haram (Prohibited). Such as when a child at the time of breast feeding bites away, then the milk gets converted into blood.
