He is asking about dolls and three-dimensional toys, and whether that affects his fast
Question

                Iam working in a toy shop we also sell dolls and human shaped toys ,what is the ruling on this? and is it permissible for me to open my fast later cause of my work?.
Praise be to Allah.
    We have already explained that it is haraam to make images 
    and statues (question no.
    7222) and that it is 
    haraam to buy and sell them (question no.
    49676. 

    But if these images and dolls are toys for children, the 
    Sunnah indicates that they are permissible. In al-Saheehayn it is 
    narrated that ‘Aa’ishah (may Allaah be pleased with her) said: “I used to 
    play with dolls in the presence of the Prophet  (peace and blessings of 
    Allaah be upon him) and I had female friends who would play with me…” 
    al-Bukhaari, 6130; Muslim, 2440. 

    Ibn Hajar said: This hadeeth indicates that it is permissible 
    to have images of girls (i.e., dolls) and toys for girls to play with. This 
    is an exception from the general meaning of the prohibition on having 
    images. This was stated by ‘Iyaad and was narrated from the majority. They 
    permitted the sale of dolls to girls so as to teach them from a young age 
    how to take care of their homes and children. Ibn Hibbaan stated that it is 
    permissible for young girls to play with toys… According to a report 
    narrated by Jareer from Hishaam: “I used to play with dolls.” Narrated by 
    Abu ‘Awaanah and others. Abu Dawood and al-Nasaa’i narrated from ‘Aa’ishah 
    with a different isnaad that she said: “The Messenger of Allaah  (peace 
    and blessings of Allaah be upon him) came from the campaign of Tabook or 
    Khaybar…” and he mentioned the hadeeth about the Prophet  (peace and 
    blessings of Allaah be upon him) tearing down the curtain on which there 
    were images, that ‘Aa’ishah had put over her door. She said: And he 
    uncovered the niche in which were dolls that ‘Aa’ishah used to play with. He 
    said: “What is this, O ‘Aa’ishah?” She said: “My daughters (i.e., dolls).” 
    She said: And he saw among them a horse with two wings tied to it and said: 
    “What is this?” I said: “A horse.” He said:  “A horse with two wings?” I 
    said: “Have you not heard that Sulaymaan had horses with wings?” and he 
    smiled. 

    The report mentioned by Ibn Hajar was narrated by Abu Dawood, 
    no. 22813; classed as saheeh by al-Albaani in Ghaayat al-Maraam, 
    129. 

    Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) said: 

    With regard to that which does not have complete features and 
    just has some limbs and a head, there is no doubt that this is permissible 
    and that it comes under the same heading as the dolls with which ‘Aa’ishah 
    (may Allaah be pleased with her) used to play.  

    As for that which has complete features, as if you were 
    looking at a person, especially if it can move or has a voice, then I feel 
    hesitant to say that this is permissible, because it is imitating the 
    creation of Allaah. It seems that the toys that ‘Aa’ishah used to play with 
    were not like this, so it is better to avoid them. But I do not say that it 
    is definitely haraam, because concessions may be granted to young children 
    that are not granted to adults in such matters, because it is the natural 
    inclination of young children to play and have fun and they are not obliged 
    to do acts of worship so that we could say that a child is wasting his time 
    with this play. But if a person wants to be on the safe side, let him remove 
    the head or hold it over the fire so that it becomes soft, then he can press 
    it so that the features disappear.

    2/277-278. 

    With regard to the 
    questioner’s asking whether it is permissible to start fasting later on of 
    this work, we do not understand exactly what he 
    means. If he means that this work invalidates his fast and what is 
    prescribed is to make up the fast later on, then he should not work in this 
    haraam job. We have already explained that all sins affect the fast and 
    reduce the reward, and may cancel out the reward altogether, if he does a 
    lot of sins, but that does not invalidate the fast and he is not commanded 
    to make it up. Rather he should refrain from committing these sins at all 
    times, especially in Ramadaan. See question no.

    If the question means something else, then we hope that he 
    will explain it so that we can answer.
