Uncertainty about the number of circuits of tawaaf and how to reconcile between two scholarly opinions
Question

                Please explain I had gone through the following two views regarding doubts after 7 round executed in Tawaf:

1)But if one doubts the number of rounds while he is performing Tawaf, he has to complete his Tawaf. If one doubts the number of rounds to be either six or seven rounds, he has to perform the seventh round. But if one doubts the number of rounds after finishing Tawaf as if he thinks that he completed his Tawaf but Satan causes him to doubt his Tawaf, then his Tawaf will be valid.[ Fatawaa Shaykh Ibn Baaz]

2)..Malik said that someone who was in doubt about his tawaf after he had prayed the two rakas of tawaf should go back and complete his tawaf until he was certain of how much he had done. He should then repeat the two rakas, because prayer when doing tawaf was only valid after completing seven circuits. "

Sir , as I think ,Second option tells to consider doubt even after the act of worship had been finished. Whereas First option tells that just after executing the current stage you do not bother. For example, do not bother about no of round after 7 round executed . Though prayer of Tawaf is still left to be offered .How will you reconcile them.
Praise be to Allah.
    Firstly: 

    With regard to uncertainty about the number of circuits 
    performed, one of two scenarios must apply: 

    1.He is still performing the act 
    of worship. In this case, he should proceed on the basis of the lesser 
    number. If he is not sure whether he did five or six circuits, he should 
    assume that he did the lesser number, i.e., five, because this is what is 
    certain, but there is some doubt about the higher number (i.e., six). The 
    evidence for that is the words of the Prophet (blessings and peace of Allah 
    be upon him): “If one of you is uncertain about his prayer and does not know 
    whether he prayed three or four (rak‘ahs), let him ignore the uncertainty 
    and proceed on the basis of that which he is certain of.”

    Narrated by Muslim, 888 

    Ibn Qudaamah (may Allah have mercy on him): If he is not sure 
    of the number of circuits, he should proceed on the basis of what he is 
    certain of. Ibn al-Mundhir said: All of the scholars from whom we learned 
    are agreed on that. And because it is an act of worship, so if one is 
    uncertain about it whilst still doing it, he should proceed on the basis of 
    what he is certain of, as in the case of prayer.

    2.If the uncertainty arises after 
    one has finished the act of worship. In that case he should not pay any 
    attention to it, according to the correct scholarly view, because the basic 
    principle is that acts of worship are free of shortcomings, so that one will 
    not open the door to waswasah (whispers from the Shaytaan).

    It says in al-Mawsoo‘ah al-Fiqhiyyah, 29/125: If he is 
    uncertain after finishing tawaaf, he should not pay any attention to that, 
    according to the majority of scholars, apart from the Maalikis who regarded 
    doubt during tawaaf or after finishing it as being the same. End quote. 

    Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) said: 
    Uncertainty after completing an act of worship does not mean anything. For 
    example, if a person is unsure as to whether he did five or six circuits of 
    tawaaf, we say: If that arises during tawaaf, he should do that which he is 
    uncertain of, and that is the end of the matter. If that arises after he has 
    finished tawaaf and moved away, and he says: By Allah, I do not know whether 
    I did six or seven circuits, that uncertainty does not mean anything. So he 
    should ignore the uncertainty and assume that he did seven. 

    This is a useful principle: if a person feels a great deal of 
    uncertainty, he should not pay any attention to it, and if the uncertainty 
    arises after he has finished the act of worship, he should not pay any 
    attention to it unless he is certain. If he is certain then he has to do 
    what he omitted.
